Window RAM

From Academic Kids

(Redirected from WRAM)

Window RAM or WRAM is an obsolete type of semiconductor computer memory that was designed to replace video RAM (VRAM) in graphics adapters. It was developed by Samsung and also marketed by Micron Technology, but had only a short market life before being superseded by SDRAM (synchronous DRAM) and SGRAM (synchronous graphics RAM).

WRAM has a dual-ported dynamic RAM structure similar to that of VRAM, with one parallel port and one serial port, but has extra features to enable fast block copies and block fills (so-called window operations). It has a 32-bit wide host port to enable optimal data transfer in PCI and VESA Local Bus systems. It is sometimes erroneously called Windows RAM, because of confusion with the Microsoft Windows operating systems, to which it is unrelated.
