PROBLEM TO BE SOLVED: To provide a write-in/erasion control method for flash memory by which a test time for write-in/erasion can be shortened by eliminating a verification operation at the time of initial eration. ;SOLUTION: In the flash memory performing write-in and erasion of plural...
A write buffer buffers write data, thereby allowing refresh operations to be performed when consecutive write accesses hit the address range of a single memory bank for a long period of time. Both the read and write buffers can be constructed of DRAM cells. 展开 ...
