    摘要: A memory device comprises a memory array, a status register coupled with the memory array, and a security register coupled with the memory array and the status register. The memory array contains a number of memory blocks configured to have independent access control. The status register includes at least one protection bit indicative of a write-protection status of at least one corresponding block of the memory blocks that corresponds to the protection bit. The security register includes at least one register-protection bit. The register-protection bit is programmable to a memory-protection state for preventing a state change of at least the protection bit of the status register. The register-protection bit is configured to remain in the memory-protection state until the resetting of the memory device.

    摘要: Various embodiments increase the speed of communication over a multi-mode bus by communicating data over multiple pins in the same direction. The bus includes multiple data communication pins communicating over the bus. The bus includes a chip select pin indicating whether communication is occurring between the integrated circuit and another integrated circuit. The bus includes a clock pin. The bus includes a mode control circuit. In one mode, two of the data communication pins communicate in opposite directions between the integrated circuit and another integrated circuit. In another mode, two of the data communication pins communicate in a same direction between the integrated circuit and another integrated circuit. In some embodiments, the bus follows a Serial Peripheral Interface standard. In various embodiments, data is communicated from the integrated circuit to another integrated circuit, or from another integrated circuit to the integrated circuit.

    摘要: A memory and method for charging a word line thereof are disclosed. The memory includes a first word line driver, a first word line and a first switch. The first word line driver is connected to a first operational voltage for receiving a first control signal. The first word line comprises a start terminal connected to an output terminal of the first word line driver. The first switch is connected to a second operational voltage and an end terminal of the first word line. The second operational voltage is not smaller than the first operational voltage. When the first word line driver is controlled by the first control signal to start charging up the first word line, the first switch is simultaneously turned on to provide another charging path for the first word line until the first word line is charged to the first operational voltage.

    摘要: Memory cells of a nonvolatile memory array are characterized by one of multiple threshold voltage ranges including at least an erased threshold voltage range and a programmed threshold voltage range. Responsive to an erase command to erase a group of memory cells of the nonvolatile memory array, a plurality of phases are performed, including at least a pre-program phase and an erase phase. The pre-program phase programs a first set of memory cells in the group having threshold voltages within the erased threshold voltage range, and does not program a second set of memory cells in the group having threshold voltages within the erased threshold voltage range in the group. By not programming the second set of memory cells, the pre-program phase is performed more quickly than if the second set of memory cells were programmed along with the first set of memory cells.
