NT5DS16M16DS-6K – 256Mb DDR SDRAM – Nanya

The Nanya NT5DS16M16DS-6K is a 256Mb DDR SDRAM organized as 16M x 16 in a 66-pin TSOP II package, rated for DDR333 (166 MHz) operation. An obsolete, hard-to-find memory device available for quote from Pacific Component Xchange.

The Nanya NT5DS16M16DS-6K is a 256-megabit Double Data Rate (DDR) Synchronous DRAM from Nanya Technology’s NT5DS family. It is internally organized as a 16M x 16 (16 Meg words x 16 bits) device built on a quad-bank architecture, delivering 268,435,456 bits of total storage. The “-6K” speed grade corresponds to DDR333 operation (166 MHz clock, 333 MT/s) with a CAS latency of 2.5 (CL2.5-3-3).

Based on a double-data-rate architecture, the device transfers two data words per clock cycle at the I/O pins using a bidirectional data strobe (DQS) and differential clock inputs (CK / CK#). It is well suited for legacy embedded systems, networking line cards, industrial controllers, and other long-lifecycle designs that still rely on classic DDR1 memory.
