Claim Text:
1. An apparatus, comprising: a plurality of data storage cells; circuitry configured to store test data in a first subset of the plurality of data storage cells; and a first regulation circuit configured to modify a first voltage level supplied to a first power terminal coupled to each data storage cell included in the first subset of the plurality of data storage cells from a first value to a second value; a second regulation circuit configured to modify a second voltage level supplied to a second power terminal coupled to each data storage cell included in a second subset of the plurality of data storage cells; wherein the circuitry is further configured to perform a first read operation on the first subset of data storage cells in response to the modification of the voltage level; wherein the first regulation circuit is further configured to modify the first voltage level from the second value to the first value; and wherein the circuitry is further configured to:
