Description

M2U51264DS8HB3G, M2U25664DS88B3G, and M2U12864DSH4B3G are unbuffered 184-Pin Double Data Rate (DDR) Synchronous

DRAM Dual In-Line Memory Modules (DIMM). M2U51264DS8HB3G is 512MB modules organized as dual ranks using sixteen 32Mx8

TSOP devices. M2U25664DS88B3G is 256MB modules organized as single rank using eight 32Mx8 TSOP devices. M2U12864DSH4B3G

is 128MB modules, organized as single rank using four 16Mx16 TSOP devices.

Depending on the speed grade, these DIMMs are intended for use in applications operating up to 200 MHz clock speeds and achieves

high-speed data transfer rates of up to 400 MHz. Prior to any access operation, the device CAS latency and burst type/ length/operation

type must be programmed into the DIMM by address inputs and I/O inputs BA0 and BA1 using the mode register set cycle.

The DIMM uses a serial EEPROM and through the use of a standard IIC protocol the serial presence-detect implementation (SPD) can be

accessed. The first 128 bytes of the SPD data are programmed with the module characteristics as defined by JEDEC.
