Abstract:
1. A method for reading from a memory, the method comprising: pre-charging a first node and a second node of a sense amplifier to a same voltage, wherein the first node is coupled to a power supply node through a first capacitor, and the second node is coupled to the power supply node through a second capacitor, and wherein the first capacitor has a first capacitance smaller than a second capacitance of the second capacitor; receiving a data voltage from a bit line of the memory into a data line; after the step of receiving the data voltage, receiving a fixed voltage into the sense amplifier, wherein the fixed voltage is connected to the first node in the sense amplifier; and at a time the fixed voltage is received, simultaneously receiving the data voltage on the data line into the sense amplifier, wherein the voltage is received to the second node.
