Description
This is the IBM21S751PFC electronic component model, which falls under the product category of IC Chips. It is a 4Mb dual port Video RAM (VRAM) that consists of a Dynamic Random Access Memory (DRAM) organized as 256K x 16, interfaced to a Serial Register / Serial Access Memory (SAM) organized as 256 x 16.
The VRAM supports three basic operations, including bidirectional random access to the DRAM, bidirectional serial access to the SAM, and bidirectional data transfer between any DRAM row and the SAM. It offers full compatibility between Half Depth SAM (256 x 16) and Full Depth SAM (512 x 16) by setting the VRAM in Serial Register Stop (SRS) mode with a stop address of 128 bit (or less).
