HYM 64(72)V2005GU-50/-60
2M x 64/72 DRAM Module
The HYM64(72)V2005GU-50/-60 are industry standard 168-pin 8-byte Dual In-Line Memory
Modules (DIMMs) which are organized as 2M x 64 and 2M x 72 high speed memory arrays
designed with EDO DRAMs for non-parity and ECC applications. The DIMMs use eight 2M x 8 EDO
DRAMs for the 2M x 64 organisation and nine 2M x 8 DRAMs for the 2M x 72 organisation, both in
SOJ packages. Decoupling capacitors are mounted on the PC board.
The DIMMs use optional serial presence detects implemented via a serial E ²PROM using the two
pin I²C protocol. The first 128 bytes are utilized by the DIMM manufacturer and the second 128
bytes of serial PD data are available to the customer.
All 168-pin DIMMs provide a high performance, flexible 8-byte interface in a 133,35 mm long space-
saving footprint.
