    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 multi-input/output serial peripheral interface of an integrated circuit includes many pins coupled to the integrated circuit. The integrated circuit receives an instruction under a control of selectively using only a first pin or a combination of the first pin, a second pin, a third pin, and a fourth pin of the multi-input/output serial peripheral interface. The integrated circuit receives an address using the first pin, the second pin, the third pin, and the fourth pin of the multi-input/output serial peripheral interface. The integrated circuit sends a read out data using the first pin, the second pin, the third pin, and the fourth pin of the multi-input/output serial peripheral interface.
