Abstract:
Precharging circuits and techniques are presented for use with magnetic memory devices in order to speed up access to the memory cells for reading and writing. Including precharging in the sense amplifiers used to access the memory cells enables self-referenced read operations to be completed more quickly than is possible without precharging. Similarly, precharging can also be used in conjunction with write-back operations in order to allow the data state stored by magnetic tunnel junctions included in the memory cells to be changed more rapidly.

Claim (Index 21):
A method of operation of a memory cell that includes a magnetic tunnel junction having a first end and a second end, comprising:\n applying a read voltage across the magnetic tunnel junction using a first circuit coupled between a first node and a first line, wherein the first line is coupled to the first end of the magnetic tunnel junction; while applying the read voltage, sampling a sample voltage on the first node, wherein the sample voltage results from current flow through the magnetic tunnel junction based on the read voltage on the first line; after sampling the sample voltage, applying a first write current through the magnetic tunnel junction to place the magnetic tunnel junction in a known first state; after applying the first write current:\n precharging the first line to a low voltage; \n after precharging the first line to the low voltage, re-applying the read voltage across the magnetic tunnel junction; and \n comparing the sample voltage with an evaluation voltage on the first node to determine an initial state of the magnetic tunnel junction, wherein the evaluation voltage results from re-applying the read voltage.
