摘要： Peripheral devices store data in non-volatile phase-change memory (PCM). PCM cells have alloy resistors with high-resistance amorphous states and low-resistance crystalline states. The peripheral device can be a Multi-Media Card/Secure Digital (MMC/SD) card. A PCM controller accesses PCM memory devices. Various routines that execute on a CPU in the PCM controller are activated in response to commands in the host-bus transactions. The PCM system increases the throughput of one or more phase-change memory devices by performing one or more of a read-ahead memory operation, a write-ahead memory write operation, a larger page memory write operation, a wider data bus memory write operation, a multi-channel concurrent multi-bank interleaving memory read or write operation, a write-cache memory write operation, and any combination thereof.

摘要： A secure flash-card reader reads a user ID from a secure card and finds a matching entry with a hashed password in a user table on the reader. An encrypted key is received from a secure host that hashes and encrypts a password the user types into the host and the user's ID. A card decryption engine uses a random number to decrypt the encrypted key and recover the hashed password and user ID from the secure host, which is compared by a comparator to the hashed password and user ID from the user table. A mismatch causes an access controller to block access to encrypted data on the secure card. Flash data is transferred over a flash-serial buffer bus between flash-card controllers and a RAM buffer. An encryption engine on the flash-serial buffer bus encrypts and decrypts data and connects to a serial engine to the host.

摘要： A multi-ring memory controller sends request packets to multiple rings of serial flash-memory chips. Each of the multiple rings has serial flash-memory chips with serial links in a uni-directional ring. Each serial flash-memory chip has a bypassing transceiver with a device ID checker that bypasses serial packets to a clock re-synchronizer and bypass logic for retransmission to the next device in the ring, or extracts the serial packet to the local device when an ID match occurs. Serial packets pass through all devices in the ring during one round-trip transaction from the controller. The average latency of one round is constant for all devices on the ring, reducing data-dependent performance, since the same packet latency occurs regardless of the data location on the ring. The serial links can be a Peripheral Component Interconnect (PCI) Express bus. Packets have modified-PCI-Express headers that define the packet type and data-payload length.

摘要： A restrictive multi-level-cell (MLC) flash memory prohibits regressive page-writes. When a regressive page-write is requested, an empty block having a low wear-level count is found, and data from the regressive page-write and data from pages stored in the old block are written to the empty block in page order. The old block is erased and recycled. A two-level look-up table is stored in volatile random-access memory (RAM). A logical page address from a host is divided by a modulo divider to generate a quotient and a remainder. The quotient is a logical block address that indexes a first-level look-up table to find a mapping entry with a physical block address that selects a row in a second-level look-up table. The remainder locates a column in the row in the second-level look-up table. If any page-valid bits above the column pointed to by the remainder are set, the write is regressive.

摘要： An adaptable-capacity Secure Digital (SD) card operates as a standard-capacity SD card for a standard-capacity SD 2.0 or 1.x host, and operates as a high-capacity SD card when connected to a high-capacity SD 2.0 host. A 32-bit argument received in a SD bus transaction from the host may be a 32-bit address, which can access 4 G bytes of flash memory in standard-capacity mode. For high-capacity mode, the addressable unit is a 512-byte sector, greatly increasing the addressable memory size. A SD protocol interface on a controller chip performs handshaking with the host to determine the SD version and memory capacity of the host. Host addresses are sent as byte or sector addresses to a flash memory manager on the controller chip, depending on the capacity mode agreed on during the handshaking. Memory areas on the adaptable-capacity SD card for high and standard modes can be separate or overlapping.
摘要翻译：适用于容量的安全数字（SD）卡作为标准容量SD 2.0或1.x主机的标准容量SD卡运行，并连接到大容量SD 2.0主机时作为高容量SD卡运行。来自主机的SD总线事务中接收到的32位参数可以是32位地址，可以在标准容量模式下访问4 G字节的闪存。对于高容量模式，可寻址单元是一个512字节的扇区，大大增加了可寻址的存储器大小。控制器芯片上的SD协议接口与主机执行握手，以确定主机的SD版本和内存容量。主机地址作为字节或扇区地址发送到控制器芯片上的闪存管理器，这取决于握手期间商定的容量模式。适用于高容量SD卡的存储区域可以分开或重叠。

摘要： A dual-voltage secure digital (SD) card can be inserted into a legacy host or a newer host. Legacy hosts drive a high voltage such as 3.3 volts onto the power line of the SD bus, while newer hosts drive the power line with a reduced voltage such as 1.8 volts. A flash and voltage controller chip on the SD card has a controller core that operates at the reduced voltage. A voltage regulator on the SD card, or a power management unit inside the controller chip generates an internal power voltage of 1.8 volts from the dual-voltage SD bus power line. The internal power voltage is applied to the controller core and to a voltage converter that generates a flash power voltage from the internal power voltage. The flash power voltage is applied to flash-memory chips on the SD card that operate at the higher voltage.

The IC chips include, for example, a USB controller chip and a flash memory chip, or a single-chip (combined USB controller/flash memory) chip. Multiple flash IC chips are optionally stacked to increase storage capacity. The IC chip(s) are attached to the PCB by wire bonding or other chip-on-board (COB) technique. The passive components are attached by conventional surface mount technology (SMT) techniques. A molded housing is then formed over the IC chips and passive components such that the device has a uniform thickness.

摘要： In an electronic data storage device accessed by a host computer motherboard, a fingerprint sensor scans a fingerprint of a user of the electronic data storage device and generates fingerprint scan data. A processing unit activates an input/output interface circuit to store a data file and fingerprint reference data obtained by scanning a fingerprint of a person authorized to access the data file in a memory device having non-volatile memory, where the processing unit transmits the data file to the host computer motherboard upon verifying that the user of the electronic data storage device is authorized to access the data file stored in the memory device as a result of comparison between the fingerprint scan data from the fingerprint sensor and the fingerprint reference data. Other methods and apparatuses are also described.

摘要： A pen-type computer peripheral device includes an elongated housing containing a PCBA having a plug connector and a fingerprint sensor mounted thereon. The PCBA is secured to a positioning member that is actuated by way of a press-push button that is exposed through a slot defined in a wall of the housing. By pressing and pushing (sliding) the press-push button along the slot, the fingerprint sensor and the plug connector are moved between a retracted position, in which the fingerprint sensor is positioned inside of the housing and the plug connector is covered by a portion of the housing wall, and a deployed position in which the fingerprint sensor is exposed through the slot and the plug connector extends through a front housing opening such that both the fingerprint sensor and the plug connector are exposed outside of the housing.
