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 32):
An apparatus comprising:\n a memory cell that includes a magnetic tunnel junction coupled in series with a selection transistor; preamplifier circuitry coupled to a first end of the memory cell by a first line, wherein the preamplifier circuitry includes a capacitor; a first NMOS-follower circuit coupled to the first line; a first precharge transistor coupled between the first line and a first low voltage source; and control circuitry coupled to the preamplifier circuitry, the first NMOS-follower circuit, and a gate of the first precharge transistor, the control circuitry configured to:\n apply a read voltage across the magnetic tunnel junction during a first sense phase using the preamplifier circuitry, wherein a sample voltage corresponding to current through the magnetic tunnel junction as a result of the read voltage is stored in the capacitor during the first sense phase; \n after the first sense phase, apply a first write current through the magnetic tunnel junction using the first NMOS-follower circuit, wherein the first write current places the magnetic tunnel junction in a known first state; and \n after applying the first write current, apply a voltage pulse to the gate of the first precharge transistor such that the first precharge transistor pulls the first line to a low voltage after the magnetic tunnel junction is placed in the known first state.
