Description
   The HYS64D64300[G/H]U–[5/6]–B, HYS72D64300[G/H]U–[5/6]–B, HYS64D128320[G/H]U–[5/6]–B, and HYS72D128320[G/H]U–[5/6]–B are industry standard 184-Pin Unbuffered Dual-In-Line Memory Modules (UDIMM) organized as 64M ×64, 128M ×64 for non-parity and 64M ×72,128M ×72 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
