Description
   The Qimonda HYS64D32301[G/H]U–5–B, HYS[64/72]D64xxx[G/H]U– [5/6]–B and HYS[64/72]D128xxx[G/H]U–[5/6]–B are industry standard 184-Pin Unbuffered Double-Data-Rate Memory Modules (UDIMM) organized as 32M × 64M (256 MB), 64M ×64 (512 MB), 128M ×64 (1 GB) for non-parity and 64M ×72 (512 MB), 128M ×72 (1 GB) for ECC main memory applications. The memory array is designed with 512Mbit Double Data Rate Synchronous DRAMs. A variety of decoupling capacitors are mounted on the printed circuit board. The DIMMs feature serial presence detect (SPD) based on a serial E2PROM device using the 2-pin I2C protocol. The first 128 bytes are programmed with configuration data and the second 128 bytes are available to the customer.
