HSD128M72B9K
Synchronous DRAM Module 1024Mbyte (128Mx72Bit), 8K Ref., 3.3V
ECC Unbuffered SO-DIMM,
Part No. HSD128M72B9K
GENERAL DESCRIPTION
The HSD128M72B9K is a 128M x 72 bit Synchronous Dynamic RAM high density memory module. The module
consists of nine CMOS 128M x 8 bit with 4banks Synchronous DRAMs in TSOP-II 400mil packages on a 144-pin glass-
epoxy substrate. One or two 0.1uF decoupling capacitors are mounted on the printed circuit board in parallel for each
SDRAM. The HSD128M72B9K is a SO-DIMM(Small Outline Dual in line Memory Module) and is intended for mounting
into 144-pin edge connector sockets. 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.
