Description
   The HYS64D32020GDL–[5/6/7/8]–B and HYS64D1600xGDL–[6/7/8]–B are industry standard 200-Pin Small Outline Dual-In-Line Memory Modules (SO-DIMMs) organized as 32M × 64 and 16M × 64. The memory array is designed with Double Data Rate Synchronous DRAMs (DDR SDRAM). 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.
