DescriptionThe Qimonda HYS64T module family are small outline DIMM modules "SO-DIMMs" with 30 mm height based on DDR2 technology. DIMMs are available as non-ECC modules in 32M * 64 (256 MB), 64M * 64 (512 MB) and 128M * 64 (1 GB) organization and density, intended for mounting into 200-pin connector sockets.
The memory array of the HYS64T is designed with 512-Mbit Double-Data- Rate-Two (DDR2) Synchronous DRAMs. Decoupling capacitors are mounted on the PCB 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 are write protected;the second 128 bytes are available to the customer.
