Description

The HM538253B/HM538254B is a 2-Mbit multiport video RAM equipped with a 256-kword

RAM and a 512-word

asynchronously. The HM538253B/HM538254B is upwardly compatible with the HM534253B/HM538123B

except that the pseudo-write-transfer cycle is replaced with masked-write-transfer cycle, which has been

approved by JEDEC. Furthermore, several new features have been added to the HM538253B/HM538254B

which do not conflict with the conventional features. The stopping column feature realizes allows greater

flexibility for split SAM register lengths. Persistent mask is also installed according to the TMS34020

features. The HM538254B has Hyper page mode which enables fast page cycle.
