Description

Features

HM534253B Series

1 M VRAM (256-kword

4-bit)

E0165H10 (Ver. 1.0)

(Previous ADE-203-204D (Z))

Jul. 6, 2001 (K)

The HM534253B is a 1-Mbit multiport video RAM equipped with a 256-kword

4-bit dynamic RAM and a

512-word

4-bit SAM (serial access memory). Its RAM and SAM operate independently and

asynchronously. It can transfer data between RAM and SAM. In addition, it has two modes to realize fast

writing in RAM. Block write and flash write modes clear the data of 4-word

4-bit and the data of one row

(512-word

4-bit) respectively in one cycle of RAM. And the HM534253B makes split transfer cycle

possible by dividing SAM into two split buffers equipped with 256-word

4-bit each. This cycle can transfer

data to SAM which is not active, and enables a continuous serial access.
