ABSTRACT:
A nonvolatile memory (programmable) comprises a plurality of logic memories, each of which is composed of a plurality of memory segments. Each of the memory segments is constituted of a first nonvolatile memory area capable of storing data of a predetermined bit number and a second nonvolatile memory area containing an identifier for the corresponding first nonvolatile memory area. Each of the logical memories is given one logical address, and when write operation is executed, a controller operates to access to the logical memory identified by the inputted logical address so as to erase in the accessed logical memory the memory segment having the identifier indicating that the data is stored, and to write the inputted data to the memory segment next to the erased memory segment.
