Abstract

A memory device includes plural word data storing rows. Each word data storing row is composed of a plurality of data bit cells for storing the word data, and a valid bit cell for indicating the validity of data. The valid bit cell has a reset circuit composed of FETs, and the reset circuits are connected to one reset line. By applying a reset signal to one reset line, plural valid bit cells are reset as a batch.
