This data sheet provides information about MC-4516CB646 16M-WORD BY 64-BIT SYNCHRONOUS DYNAMIC RAM MODULE UNBUFFERED TYPE, including storage capacity, clock frequency, access time, etc.
The document describes the NEC MC-4516CB646, an unbuffered type synchronous dynamic RAM module. It is constructed by assembling eight pieces of PD45128841 SDRAM chips to provide high density memory in a small space without surface-mounting technology on the printed circuit board.
Key features include fully synchronous operation with all signals referenced to a positive clock edge, programmable burst lengths (1, 2, 4, 8, and full page), and programmable CAS latency of 2 or 3. The module operates at clock frequencies up to 125 MHz with a single 3.3V power supply.
