Description

NT128D64S88A0G 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 16Mx64 module is a single-bank DIMM that uses eight 16Mx8 DDR SDRAMs in 400 mil TSOP packages. The DIMM achieves high-speed data transfer rates of up to 266MHz. The DIMM is intended for use in applications operating from 100 MHz to 133 MHz clock speeds with data rates of 200 to 266 MHz. Clock enable CKE0 controls all devices on the DIMM.
