Abstract
A memory control circuit includes a leakage current providing circuit, a current mirror circuit, an operational circuit and a reference current adjustment circuit. The leakage current providing circuit is used to receive a control signal and provide a leakage current when the control signal has a first enable signal level. The current mirror circuit is used to generate a control current according to the leakage current. The operational circuit is used to generate an enable signal. When the control current is larger than a predetermined value, the enable signal has a second enable signal level. The reference current adjustment circuit is coupled to the operational circuit. When the enable signal has the second enable signal level, the reference current adjustment circuit generates an updated reference current according to a reference current and an adjustment current. The updated reference current is used to determine a resistance of a memory.
