  • Publication number: 20130100730
    Abstract: A memory access operation on a bit cell of a digital memory, e.g., a static random access memory (SRAM), is assisted by reducing the word line control voltage for reading and boosting it for writing, thus improving data integrity. The bit cell has cross coupled inverters for storing and retrieving a logic state via bit line connections through a passing gate transistor controlled by the word line. A level of a word line signal controlling the passing gate transistor is shifted from a first voltage value to a higher second voltage value to begin a memory access cycle. The level of the word line signal is shifted from the second voltage value to a third voltage value less than the second voltage value during the access cycle. The word line signal is maintained at the third voltage value for a time interval during the access cycle.
