Description
The Silicon Power Computer & Communications STU series products are 200-Pin Double Data
Rate 3 (DDR3) Synchronous DRAM Small Outline Dual In-Line Memory Module (SODIMM),
organized as a one rank 128Mx64 or 256Mx64, high-speed memory array or two ranks 128Mx64,
256Mx64, 512Mx64 high-speed memory array, The module uses four 128x16(1GB), eight
64Mx16(1GB), 128Mx8 (1GB), 128Mx16(2GB), 256Mx8 (2GB), 512Mx8 (4GB), sixteen 128Mx8
(2GB), 256Mx8 (4GB), 512Mx8 (8GB) DDR3 SDRAMs in BGA packages
This DIMM are manufactured using raw cards developed for broad industry use as reference
designs. The use of these common design files minimizes electrical variation between suppliers.
DDR3 SDRAM DIMM provide a high-performance, flexible 8-byte interface in a space-saving
footprint.
The DIMM is intended for use in applications operating of 533MHz, 667MHz, 800MHz clock
speeds and achieves high-speed data transfer rates of 1066, 1333, 1600Mbps. Prior to any access
operation, the device CAS latency and burst/length/operation type must be programmed into the
DIMM by address inputs A0-A12(64Mx16), A0-A13(128Mx16 or 128Mx8), A0-A14(256Mx8),
A0-A15 (512Mx8) and I/O inputs BA0~BA2 using the mode register set cycle.
The DIMM uses serial presence-detect implemented via a serial EEPROM using a standard IIC
protocol.
