MSM518222 - DRAM / FAST PAGE MODE TYPE

Description

The OKI MSM518222 is a high performance 2-Mbit, 256K

8-bit, Field Memory.

It is designed for high-speed serial access applications such as HDTVs, conventional NTSC TVs, VTRs, digital movies and Multi-media systems.

The 2-Mbit capacity fits one field of a conventional NTSC TV screen.

E2L0033-17-Y1 ¡ Semiconductor MSM518222 ¡ Semiconductor 262,214-Word ¥ 8-Bit Field Memory This version: Jan. 1998 MSM518222 Previous version: Dec. 1996 DESCRIPTION The OKI MSM518222 is a high performance 2-Mbit, 256K ¥ 8-bit, Field Memory. It is designed for high-speed serial access applications such as HDTVs, conventional NTSC TVs, VTRs, digital movies and Multi-media systems. The 2-Mbit capacity fits one field of a conventional NTSC TV screen. Two cascaded MSM518222s make one frame of the screen: two or more MSM518222s can be cascaded directly without any delay devices between them. (Cascading provides larger storage depth or a longer delay). Each of the 8-bit planes has separate serial write and read ports.
