Mimicking multi-voltage domain wordline decoding logic for a memory array |
| 摘要 |
Systems and methods for adaptively mimicking wordline decoding logic for multi-voltage domain memory are disclosed. In one embodiment, the multi-voltage domain memory includes a memory array implemented in a high voltage domain and a multi-voltage domain control circuit. The multi-voltage domain control circuit includes multi-voltage domain decoding logic that generates a wordline for the memory array and a multi-voltage domain mimic logic that mimics the multi-voltage domain decoding logic to generate a dummy wordline. In one embodiment, the dummy wordline is utilized to trigger an ending edge (e.g., a falling edge) of the wordline once the wordline is asserted. In addition or alternatively, the dummy wordline is utilized to generate one or more control signals for the memory array such as, for example, a pre-charge control signal and/or a sense amplifier enable signal. |
