GENERAL DESCRIPTION

The K4G323222M is 33,554,432 bits synchronous high data

rate Dynamic RAM organized as 2 x 524,288 words by 32 bits,

fabricated with SAMSUNG￠s high performance CMOS technology.

Synchronous design allows precise cycle control with the

use of system clock. I/O transactions are possible on every

clock cycle. Range of operating frequencies, programmable

burst length, and programmable latencies allows the same

device to be useful for a variety of high bandwidth, high performance

memory system applications.

Write per bit and 8 columns block write improves performance in

graphics systems.
