The Multibank DRAM (MDRAM) is a graphics memory that consists of multiple memory chips. In this architecture, the individual memory chips are divided into independent banks that are interconnected by a common bus
to form the multibank. Each memory bank corresponds to a partial memory of 32 KB.
Theindividual banks, which can be interleaved, can be accessed simultaneously, increasing the overall performance of the MDRAM
.MDRAMs are a type of video RAM. They are used in gafic applications and work synchronously. Because the memory capacity of the RAM is matched to the application, MDRAMs are less expensive than other VRAMs.
