131,072-word à 16-bit Multiport CMOS Video RAM
Preliminary
E0160H10 (Ver. 1.0)
(Previous ADE-203-266 (Z))
Jun. 14, 2001
The HM5316123B is a 2-Mbit multiport video
RAM equipped with a 128-kword à 16-bit dynamic
RAM and a 256-word à 16-bit SAM (full-sized
SAM). Its RAM and SAM operate independently
and asynchronously. The HM5316123B has
compatibility with the HM5316123.
