Abstract
A method for dynamically controlling sense amplifier differential margin of a memory during operation, in an integrated circuit, including a plurality of addressable units, is provided. The method includes setting the sense amplifier differential margin corresponding to the plurality of addressable units to a first value. The method further includes if a read data error occurs when data is read from a set of the plurality of addressable units, then setting the sense amplifier differential margin corresponding to the plurality of addressable units to a second value, wherein the second value is greater than the first value.
