Description

The NT5SV64M4AT, NT5SV32M8AT, and NT5SV16M16AT 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 133MHz by employing a pipeline chip architecture that synchronizes the output data to a system clock. The chip is fabricated with NTC’s advanced 256Mbit single transistor CMOS DRAM process technology.
