Hanbit Electronics HSD2M64B2
The HSD2M64B2 is a 2M x 64 bit Synchronous Dynamic RAM high density memory module. The module consists of two CMOS 512K x 32 bit with 4banks Synchronous DRAMs in TSOP-II 400mil packages on a 144-pin glass-epoxy substrate. The HSD2M64B2 is a SO-DIMM(Small Outline Dual in line Memory Module) and is intended for mounting into 144-pin edge connector sockets.GENERAL DESCRIPTION
Two 0.1uF decoupling capacitors are mounted on the printed circuit board in parallel for each SDRAM. 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 latencies allows the same device to be useful for a variety of high bandwidth, high performance memory system applications All module components may be powered from a single 3.3V DC power supply and all inputs and outputs are LVTTL-compatible.FEATURES
