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 128Mbit single transistor CMOS DRAM process technology. The device is designed to ply with all JEDEC standards set for synchronous DRAM products, both electrically and mechanically. All of the control, address, and data input/output (I/O or DQ) circuits are synchronized with the positive edge of an externally supplied clock. RAS, CAS, WE, and CS are pulsed signals which are examined at the positive edge of each externally applied clock (CK). Internal chip operating modes are defined by binations of these signals and a mand decoder initiates the necessary...
