A-Data Technology VDS7616A4A-6
The VDS7616A4A are four-bank Synchronous DRAMs organized as 2,097152 words x 16 bits x 4 banks.GENERAL DESCRIPTION
Synchronous design allows precise cycle control with the use of system clock I/O transactions are possible on every clock cycle. Range of operating frequencies, programmable burst length and programmable latencies allow the same device to be useful for a variety of high bandwidth high performance memory system applicationsFEATURES
