Abstract
There is provided a method of detecting offset in a sense amplifier of an SRAM memory unit. The method comprises using a sense amplifier of the SRAM memory unit to implement a read of a first data value stored in a memory cell of the SRAM memory unit, and measuring a first time for the sense amplifier to read the first data value. The method further comprises using the sense amplifier to implement a read of a second data value stored in a memory cell of the SRAM memory unit, and measuring a second time for the sense amplifier to read the second data value. The method then comprises calculating a difference between the first time and the second time, and determining whether an offset adjustment should be applied to the sense amplifier in dependence upon the difference between the first time and the second time.
