摘要
PROBLEM TO BE SOLVED: To provide a memory by which a high-speed write-through operation can be performed by a method wherein the density and the speed of an ordinary single-port memory cell are coupled to a possibility that a read access operation and a write access operation are executed in the same cycle. ;SOLUTION: A virtual two-port memory uses a single-port memory cell 200. A meand 260 for comparison compares a read address AR with a write address AW. A means 270 by which data is written into the cell 200 from a data input terminal 250 by-passes the data also to a data output terminal 280 in such a way that, when the read address AR agrees with the write address AW, a write-through operation is enabled.;COPYRIGHT: (C)1999,JPO
