  • Patent number: 8958237
    Abstract: An apparatus and method for executing a write operation in a static random access memory (SRAM) array including memory cells that are coupled to a plurality of word lines and to a plurality of bit lines are provided. A clock signal is generated to start a write operation. A pulse is generated on the plurality of word lines in response to the clock signal. An operation voltage of the SRAM array is lowered for a period of time during the write operation. The period of time is controlled and the pulse is ended using a tracking circuit. The tracking circuit includes a plurality of tracking memory cells. The plurality of tracking memory cells have a timing characteristic that emulates a timing characteristic of the SRAM array during the write operation. The tracking circuit controls the period of time and ends the pulse based on the emulated timing characteristic.

  • Patent number: 8837207
    Abstract: A static memory and a static memory cell are provided. The static memory cell includes a first transistor, a second transistor, a third transistor, a fourth transistor, a fifth transistor, a sixth transistor, a first switch, a second switch, a third switch, a first pull-down switch, and a second pull-down switch. When a data writing operation is performed, the latching capability of the latch circuit constituted by the first to the sixth transistors is disabled by turning off the second transistor or the fifth transistor, so that the speed of the data writing operation is increased and the data writing performance is improved. The first switch and the second switch provide a path for reading or writing data, and the third switch is coupled to a bit line for receiving data from or transmitting data to the bit line.
