DESCRIPTION
The ICSI IC42S32200 and IC42S32200L is a high-speed CMOS configured as a quad 512K x 32 DRAM with a synchronous interface (all signals are registered on the positive edge of the clock signal,CLK).
Each of the 512K x 32 bit banks is organized as 2048 rows by 256 columns by 32 bits.Read and write accesses start at a selected locations in a programmed sequence. Accesses begin with the registration of a BankActive command which is then followed by a Read or Write command
