摘要： A flip-flop circuit includes a precharge circuit that outputs a charge signal high when a received clock signal is LOW. A delay clock input circuit generates a delayed clock input controlled signal with the same value as an input signal when the clock signal is HIGH. A charge keeper circuit, upon receiving the charge signal and the delayed clock input controlled signal, generates a charge keeping signal, which equals the charged signal when the clock signal is LOW and equals the delayed clock input controlled signal when the clock signal is HIGH. A separator circuit can receive the charge keeping signal and clock signal and generate an inverted charge keeping signal. A storage circuit is configured to receive the inverted charge keeping signal, a present state signal, and inverted present state signal, and to generate a present state signal and an inverted present state signal.

摘要： A device includes a tag cache memory array; a pre-parity unit configured to receive an address, and calculate and output a pre-parity bit calculated from all bits of the address. A comparator is configured to compare a tag read from the tag cache memory array with the address, and output a read-hit bit. The read-hit bit is true when the tag and the address are identical, and is false when the tag and the address are not identical. The device further includes a simplified parity-check unit configured to receive and perform operations on the pre-parity bit, the read-hit bit, and a parity bit from the tag cache memory array, and to output a read-parity bit.

摘要： Circuits and methods for transmitting and receiving small swing differential voltage data to and from a memory are described. A plurality of memory cells is formed in arrays within a plurality of memory banks. Each memory bank is coupled to a pair of small swing differential voltage global bit lines that extend across the memory. A small signal write driver circuit is coupled to the global bit lines and configured to output a small signal differential voltage on the global bit lines during write cycles. A global sense amplifier is coupled to the global bit line pairs and configured to output a full swing voltage on a data line during a read cycle. Methods for providing small swing global bit line signals to memory cells are disclosed. The use of small swing differential voltage signals across the memory reduces power consumption and shortens memory cycle time.

摘要： An internal clock gating apparatus comprises a static logic block and a domino logic block. The static logic block is configured to receive a clock signal and a clock enable signal. The domino logic block is configured to receive the clock signal and a control signal from an output of the static logic block. The static logic block and the domino logic block are further configured such that an output of the domino logic block generates a signal similar to the clock signal in phase when the clock enable signal has a logic high state. On the other hand, the output of the domino logic block generates a logic low signal when the clock enable signal has a logic low state. Furthermore, the static logic block and the domino logic block can reduce the setup time and delay time of the internal clock gating apparatus respectively.

摘要： An SRAM write assist apparatus comprises a timer unit and a voltage divider. The voltage divider unit is configured to divide a voltage potential down to a lower level. The output of the voltage divider is connected to a memory cell in a write operation. The timer unit is configured to generate a pulse having a width inversely proportional to the voltage potential applied to a memory chip. Furthermore, the timer unit controls the period in which a lower voltage from the output of the voltage divider is applied to the memory cell. Moreover, external level and timing programmable signals can be used to further adjust the voltage divider's ratio and the pulse width from the timer unit. By employing the SRAM write assist apparatus, a memory chip can perform a reliable and fast write operation.
