WRITE DRIVER AND PROGRAM DRIVER FOR OTP (ONE-TIME PROGRAMMABLE) MEMORY WITH MAGNETIC TUNNELING JUNCTION CELLS

摘要

A one-time programmable (OTP) memory having a plurality of cells (102), each cell (102) having a magnetic tunnel junction (MTJ) device; and the OTP memory further including a write driver (136) to drive each MTJ device to an anti-parallel state, and a program driver (139) to drive a subset of the MTJ devices to a blown state depending upon the information to be stored.
