Abstract
One embodiment of the invention includes a memory system. The system comprises a memory cell coupled to a bit-line node. The memory cell can be configured to generate a bit-line current on the bit-line node in response to a bias voltage during a read operation. The system further comprises a sense amplifier configured to maintain a substantially constant voltage magnitude of the bit-line node during a pre-charge phase and a sense phase of the read operation based on regulating current flow to and from the bit-line node, and to determine a memory value of the flash memory transistor during the read operation based on a magnitude of the bit-line current on the bit-line node.
