    摘要: A high speed self-resetting, edge-triggered CMOS (SRCMOS) receiver and parallel L1/L2 latch combination are provided which may be used to receive and latch data from a single-ended input of static random access memory (SRAM) or a dynamic random access memory (DRAM). The invention comprises a true/complement generator circuit (TCG) for generating a data and its complement from a single-ended input, a reset circuit for automatically resetting the TCG independent of the system clock, and a parallel L1/L2 latch for storing the data for further processing. The L1/L2 latch preferably has scan-in and scan-out ports useful for testing and diagnostic purposes.

    摘要: A high performance "two stage" (or cascading) Self-resetting CMOS (SRCMOS) amplifier where the 2nd stage amplifier is self-timed off of the 1st stage. Also, the SRCMOS nature of this amplifier eliminates the need for additional reset clock signals. The net affect of this invention is that the sensing action of a SRAM cell can start sooner (relative to a single stage sensing scheme) thereby delivering the data to the outputs sooner while providing greater noise immunity when compared to traditional sense amplifiers.

    摘要: A SRCMOS sense amplifier is provided with a latch in the output stage. When a sense amplifier input signal propagates through the circuit and reaches the output stage, a reset signal is generated resetting and charging the input stage and an enable buffer stage of the amplifier to allow the input stage to begin receiving new data while previous data is latched in the output stage. An output stage reset enable is generated when data is at the output terminals of the output stage. The reset enable is combined with a clock signal in a separate output stage reset circuit to reset the circuit on a clocked basis. A further input to the output stage reset circuit is a feedback from a next circuit stage indicating that the data has been properly received in the next stage. The output stage may be reset either in response to the feedback signal from the next stage or in the presence of the reset enable and the clock signal.

    摘要: An integrated circuit can include an SRAM array having cells arranged in columns, each column being connected to true and complementary read local bitlines RLBLT and RLBLC. A local bit-select circuit can be connected to the cells of a column of the SRAM array, which can include first and second pull-down devices for pulling down a respective one of RLBLT and RLBLC at a timing controlled by a write control signal WRT. The circuit can include cross-coupled p-type field effect transistors (“PFETs”) including a first PFET having a gate connected to RLBLT and having a drain connected to RLBLC, and a second PFET of the pair having a gate connected to RLBLC and having a drain connected to RLBLT. A first device can control a strength of the cross-coupled PFETs. A pair of cross-coupled n-type field effect transistors (“NFETs”) can have gates connected to gates of the first and second pull-down devices. A second device can control a strength of the cross-coupled NFETs. The operation of the first and second devices can be controlled by applying first and second signals having programmed levels thereto. The levels of the first and second signals may selectively activate either the first device or the second device, so as to activate either the cross-coupled PFETs or the cross-coupled NFETs at one time.
