摘要： An oscillator circuit may be used with controller circuits that are designed to operate with crystals, with no modifications to the pinout or firmware of the controller circuit. In some embodiments, the oscillator circuit includes an enable input that is responsive to low-amplitude transitions, which may be coupled to and driven by the crystal output signal of the controller circuit. When transitions are present on the crystal output signal, the oscillator circuit enables its clock output signal. When the controller circuit disables its crystal output signal, the oscillator circuit no longer detects transitions on the crystal output signal coupled to the oscillator circuit enable input, and disables the clock output signal.

摘要： In a non-volatile memory (NVM) device having a controller and a non-volatile memory array controlled by the controller a voltage supervisor circuit monitors an output of a voltage supply powering the NVM device. The voltage supervisor circuit may be part of the NVM device or coupled to it. The voltage supervisor circuit is configured to assert a “low-voltage” signal responsive to detecting the output of the voltage supply powering the NVM device dropping below a predetermined value. The controller is configured to write data into the memory array while the “low-voltage” signal is deasserted and to suspend writing data while the “low-voltage” signal is asserted. In response to assertion of the “low-voltage” signal, the controller completes a write cycle/program operation, if pending, and prevents any additional write cycles/program operation(s) during assertion of the “low-voltage” signal.

摘要： A method and system have been described for counteracting and correcting for read disturb effects in blocks of flash memory. The method may include the step of a controller of the memory system performing a read scrub scan on only a portion of one targeted word line in a block at desired intervals. The controller may calculate whether a read scrub scan is necessary based on a probabilistic determination that is calculated in response to each received host read command. The controller may then place a block associated with the targeted word line into a refresh queue if a number of errors are detected in the targeted word line that meets or exceeds a predetermined threshold. The block refresh process may include copying the data from the block into a new block during a background operation.

摘要： In a nonvolatile memory that stores data in two or more different data storage formats, such as binary and MLC, a separation scheme is used to distribute blocks containing data in one data storage format (e.g. binary) so that they are separated by at least some minimum number of blocks using another data storage format (e.g. MLC).

摘要： The embodiments described herein generally use a challenge to protect a removable mobile flash memory storage device, where the challenge may be in the form of a “Completely Automated Public Turing Test to Tell Computers and Humans Apart” (“CAPTCHA”). In one embodiment, a method is provided in which a removable mobile flash memory storage device receives a command from a host device, generates a CAPTCHA challenge, provides the CAPTCHA challenge to the host device, receives a response to the CAPTCHA challenge from the host device, determines if the response satisfies the CAPTCHA challenge, and performs the command only if the response satisfies the CAPTCHA challenge. In another embodiment, a removable mobile flash memory storage device is provided for performing these acts.
