ABSTRACT:
A multiport RAM comprises a memory section formed of many unit memory cells which are positioned to an orderly matrix of M columns by N rows, a write address designation section for designating the unit memory cells on the prescribed rows, a write clock signal by which the input data is synchronized in the write operation that the data is written in the unit memory cells designated by the write address designation section, a read address designation section for designating the unit memory cells on one or more prescribed rows, and a read clock signal by which the output data is synchronized in the read operation that the data is read out from the unit memory cells designated by the read address designation section, having no relation with the write private clock signal.
