摘要： In rewriting processing of logical sectors, data of the transferred logical sectors are temporarily stored in a memory buffer. When the buffer memory has been full filled with data, the data is written into a flash memory. In rewriting processing for the flash memory including a writing unit (page) having a capacity larger than a minimum writing unit (sector) from outside, the number of executions of the evacuation processing can be reduced and the fast data rewriting can be performed. Thus, it is possible to rationalize the evacuation processing for old data caused in the rewriting in units of sectors and to improve the data rewriting speed.

摘要： Provided is a semiconductor memory device compatible with a SRAM and capable of a high-speed data transfer operation while maintaining data reliability. An access to a memory core 6 starts when an external chip enable signal XCE performs a falling transition. Simultaneously, an external write enable signal XWE and an external address signal ADD are received, and a memory cell 1, in the memory core 6, corresponding to the received external address signal ADD is selected. When a data read-out from the memory cell 1 or a data write-in to the memory cell 1 is complete, a rewrite timer 7 is activated in accordance with a rising transition of an external chip enable signal XCE or a rising transition of the external write enable signal XWE for performing a data rewrite for the memory cell 1.
