The HYS64/72D64000GU and HYS64/72D128020GU are industry standard 184-pin 8-byte Dual in-line Memory Modules (DIMMs) organized as 64M × 64 and 128M × 64 for non-parity and 64M x 72 and 128M x 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 PC board.
The DIMMs feature serial presence detect 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.
