Abstract:
1. A method for accessing a memory cell in a memory circuit, the method comprising the steps of: receiving a request to access at least one selected memory cell in the memory circuit; determining whether the at least one selected memory cell corresponds to one of a normal memory cell and a weak memory cell in the memory circuit; accessing the at least one selected memory cell using a first set of control parameters when the at least one selected memory cell corresponds to a normal memory cell, the at least one selected memory cell providing correct data under prescribed operating specifications when accessed using the first set of control parameters; and accessing the at least one selected memory cell using a second set of control parameters when the at least one selected memory cell corresponds to a weak memory cell, the at least one selected memory cell providing correct data under the prescribed operating specifications when accessed using the second set of control parameters and providing incorrect data under the prescribed operating specifications when accessed using the first set of control parameters.
