Description
NT256D64S88ABG is an unbuffered 184-Pin Double Data Rate (DDR) Synchronous DRAM Dual In-Line Memory Module (DIMM), organized as a one-bank high-speed memory array. The 32Mx64 module is a single-bank DIMM that uses eight 32Mx8 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 controls all devices on the DIMM.
