Abstract
A flash memory capable of achieving high integration and low power consumption is formed by an AND-type memory cell array, an address buffer, a row selecting/driving circuit, a column selecting circuit, an input and output circuit, and a read/write control part. A memory cell includes, for example, a charge storage layer of an ONO structure. The read/write control part performs programming and erasing by Fowler-Nordheim (FN) tunneling between the charge storage layer and a channel of a selected memory cell.
