Voltage self-boosting circuit for generating a boosted voltage for driving a word line write in a memory array for a memory write operation
A voltage self-boosting circuit for generating a boosted voltage for driving a word line write in a memory array for a memory write operation is provided. A voltage generation circuit(s) is configured to generate a read voltage for a memory read operation and a write voltage for a memory write operation based on a predefined supply voltage. For the memory write operation, a delay circuit delays the delay circuit enable signal by a predetermined delay to generate the output voltage control signal. Accordingly, the voltage generation circuit(s) generates boosted voltage that drives the write voltage to a selected word line(s). For the memory read operation, the voltage generation circuit(s) does not generate the boosted voltage and thus drives the read voltage to the selected word line(s). Hence, it is possible to reduce power consumption and timing delay during the memory read operation or the memory write operation.
