The HYS64/72D32000GU and HYS64/72D64020GU are industry standard 184-pin 8-byte Dual in-
line Memory Modules (DIMMs) organized as 32M

64 and 64M
脳
64 for non-parity and 32M x 72
and 64M x 72 for ECC main memory applications. The memory array is designed with 256Mbit
Double Data Rate Synchronous DRAMs. A variety of decoupling capacitors are mounted on the PC
board. The DIMMs feature serial presence detect based on a serial E

C protocol. The first 128 bytes are programmed with configuration data and the second 128 bytes
are available to the customer.
