NT25L90 General Description

[Nanya]DescriptionNT256D64S88A0G 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 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.Features• 184-Pin Unbuffered 8-Byte Dual In-Line Memory Module• 32Mx64 Double Data Rate (DDR) SDRAM DIMM• Performance :• Intended for 100 MHz and 133 MHz applications• Inputs and outputs are SSTL-2 compatible• VDD = 2.5Volt ± 0.2, VDDQ = 2.5Volt ± 0.2• Single Pulsed RAS interface• SDRAMs have 4 internal banks for concurrent operation• Module has one physical bank• Differential clock inputs• Data is read or written on both clock edges• DRAM DLL aligns DQ and DQS transitions with clock transitions.
