GENERAL DESCRIPTION

This 64Mb SyncFlash? data sheet is divided into two major sections. The SDRAM Interface Functional Description details compatibility with the SDRAM memory, and the Flash Memory Functional Description specifies the symmetrical-sectored Flash architecture and functional commands.
