摘要： A mobile telephone (52) comprises a flash memory (3) having a sector data structure. A flash memory (3) has a sector data structure and stores user data (UD) and a firmware (FW) in a sector unit. A user data buffer (4A) and a firmware buffer (4B) are random accessible memories. The buffers (4A) and (4B) store the user data (UD) and firmware (FW) transferred from the memory (3) together with recognition numbers thereof, respectively. As a result of retrieval in the buffer (4B) which is carried out by a CPU (1), when the firmware (FW) required for the execution of an operation input by a user is not present in the buffer (4B), the CPU (1) controls a sequencer (2) to transfer the necessary firmware (FW) from the memory (3) to the buffer (4B). The CPU (1) executes the operational contents by utilizing the firmware (FW) in the buffer (4B). The CPU (1) also utilizes the user data (UD) in the same manner as the firmware (FW).

摘要： A memory card includes a volatile memory device, and a power supply supplying an electric voltage to the memory device while the memory card is connected to a host. A timer is started when the memory card is connected to the system. A current detector detects a current flow between a pair of terminals connected to a host. A power supply controller provided between the memory device and the power supply opens repetitively when the current detector does not detect a prescribed current flow before the timer completes a prescribed timing cycle. Thus, the memory card can be accessed only when it is connected to a host having a security function in correspondence to the memory card, while it clears the data stored therein when it is connected to a host which does not correspond to the memory card. Preferably, the current detector is activated by an active signal received from a host. The memory card may also include a timer activated when the memory card is connected to the host or when an active signal is supplied from the host. The memory card also includes at least one pair of terminals connected to corresponding terminals of the host, a current detector detecting current flow between the terminals, and a power supply controller for opening repetitively between the memory device and the power supply when the current detector does not detect a prescribed current flow before the timer completes a prescribed timing cycle.

摘要： An IC memory device reduces the time required to complete operations for reading, writing, or erasing data continuously from the same sector address in plural memory chips by accomplishing said operations with a single command and sector address input operation. This IC memory device comprises a data control unit, a command control unit, and a serial clock signal generator. The data control unit handles command and data I/O operations between a data bus and the memory chips. The command control unit generates and applies a chip enable signal to each corresponding memory chip based on externally supplied command data. The serial clock signal generator generates an internal serial clock signal supplied to each memory chip based on an externally supplied serial clock signal. Data can thus be read, written, or erased continuously at the same sector address in plural memory chips with the operating command and sector address being input only once.

摘要： A two-valued flash memory (2) and multivalued flash memories (31-33) are mixed in a flash memory group (200) so that management data and user data are stored into the two-valued flash memory (2) and the multivalued flash memories (31-33), respectively. A CPU (4) operates based on universal physical addresses. On the other hand, a two-valued/multivalued selector (7), and a two-valued flash sequencer (6a) and a multivalued flash sequencer (6b) in a flash interface (6) operate based on individual physical addresses so that the management data and the user data to be transmitted/received are divided among the two-valued flash memory (2) and the multivalued flash memories (31-33). This increases storage capacity and transfer rate of a flash storage medium.
