These synchronous devices achieve high-speed data transfer rates of up to 200MHz by employing a pipeline chip architecture that synchronizes the output data to a system clock. The chip is fabricated with NTC’s advanced 64Mbit single transistor CMOS DRAM process technology. The device is designed to comply with all JEDEC standards set for synchronous DRAM products, both electrically and mechanically. All of the control, address, and data input/out- put (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 exam- ined at the positive edge of each externally applied clock (CK). Internal chip operating modes are defined by combina- tions of these signals and a command decoder initiates the necessary timings for each operation. A fourteen bit address bus accepts address data in the conventional RAS/CAS mul- tiplexing style. Twelve row addresses (A0-A11) and two bank select addresses (BS0, BS1) are strobed with RAS. Eleven column addresses (A0-A9) plus bank select addresses and A10 are strobed with CAS. Column address A9 is dropped on the x8 device, and column addresses A8 and A9 are dropped on the x16 device. Prior to any access operation, the CAS latency, burst length, and burst sequence must be programmed into the device by address inputs A0-A11, BS0, BS1 during a mode register set cycle. In addition, it is possible to program a multiple burst sequence with single write cycle for write through cache oper- ation. Operating the four memory banks in an interleave fashion allows random access operation to occur at a higher rate than is possible with standard DRAMs. A sequential and gap- less data rate of up to 200MHz is possible depending on burst length, CAS latency, and speed grade of the device. Simultaneous operation of both decks of a stacked device is allowed, depending on the operation being done. Auto Refresh (CBR) and Self Refresh operation are supported. -6K -7K -7 Units fCK Clock Frequency 166 133 143 133 143 MHz tCK Clock Cycle 6 7.5 7 7.5 7 ns CL CAS Latency CL=3 CL=2 CL=3 CL=2 CL=3 CKs tAC Clock Access Time1 --- — --- — — ns tAC Clock Access Time 2 5.4 5.4 5.4 5.4 5.4 ns 1.
