Description
NT256D64S8HA0G-6 is an unbuffered 184-Pin Double Data Rate (DDR) Synchronous DRAM Dual In-Line Memory Module (DIMM),
organized as a dual-bank high-speed memory array. The 32Mx64 module is a two-bank DIMM that uses sixteen 16Mx8 DDR
SDRAMs in 400 mil TSOP packages. The DIMM achieves high-speed data transfer rates of up to 333MHz. The DIMM is intended for use
in applications operating from 133 MHz to 166 MHz clock speeds with data rates of 266 to 333 MHz. Clock enable CKE0 and / or CKE1
controls all devices on the DIMM.
Prior to any access operation, the device CAS latency and burst type/ length/operation type must be programmed into the DIMM by
address inputs A0-A11 and I/O inputs BA0 and BA1 using the mode register set cycle.
These DIMMs 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.
The DIMM uses serial presence detects implemented via a serial EEPROM using the two-pin IIC protocol. The first 128 bytes of serial PD
data are programmed and locked during module assembly. The last 128 bytes are available to the customer.
All NANYA 184 DDR SDRAM DIMMs provide a high-performance, flexible 8-byte interface in a 5.25” long space-saving footprint.
