Abstract
A memory circuit is divided into a plurality of memory blocks, and an address register and a delay register are disposed in each memory block. Therefore, a read or write operation and a shifting operation of the address for storing data inside a memory matrix can be realized by a pipeline technique, and hence a memory circuit having a high processing speed is obtained.
