Abstract
A memory system and its programming method capable of reducing the programming time for each page, wherein the memory-cell array is constituted by a MONOS-type (MNOS-type) non-volatile memory or floating gate non-volatile memory in which a source-side channel, hot-electron injection that enables the memory to write therein data by each divided unit (for instance, each 64 bytes=512 bits) is carried out, instead of the write operation where writing is carried out collectively by each page unit (512 bytes). Further, there is provided an emulation circuit successively storing programming data that constitute the page of a plurality of divided units and a control circuit successively reading the held divided unit data so as to write to the non-volatile memory.
