GLT5640AL16 General Description
The GLT5640AL16 are high-speed 67,108,864-bit synchronous dynamic random-access memories, organized as
1,048,576 x 16 x 4 (word x bit x bank), respectively.
The synchronous DRAMs achieved high-speed data transfer using the pipeline architecture and clock frequency up
to 183MHz. All input and outputs are synchronized with the positive edge of the clock. The synchronous DRAMs are
compatible with Low Voltage TTL (LVTTL).These products are packaged in 54-pin TSOPII.
