NT5SV32M8BT Datasheet (nt5svxxmxxbx) 256mb Sdram

Manufacturer: Nanya Technology

Overview: .. NT5SV64M4BS / NT5SV64M4BT NT5SV32M8BS / NT5SV32M8BT NT5SV16M16BS / NT5SV16M16BT 256Mb Synchronous.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The NT5SV64M4BS, NT5SV64M4BT, NT5SV32M8BS, NT5SV32M8BT, NT5SV16M16BS, and NT5SV16M16BT are four-bank Synchronous DRAMs organized as 16Mbit x 4 I/O x 4 Bank, 8Mbit x 8 I/O x 4 Bank, and 4Mbit x 16 I/O x 4 Bank, respectively.

These synchronous devices achieve high-speed data transfer rates of up to 166MHz by employing a pipeline chip architecture that synchronizes the output data to a system clock.

The device is designed to ply with all JEDEC standards set for synchronous DRAM products, both electrically and mechanically.
