OTP scheme with multiple magnetic tunnel junction devices in a cell
A one time programming (OTP) apparatus unit cell includes multiple magnetic tunnel junctions (MTJs) and a shared access transistor coupled between the multiple MTJs and a fixed potential. Each of the multiple MTJs in a unit cell can be coupled to separate programming circuitry and/or separate sense amplifier circuitry so that they can be individually programmed and/or individually sensed. A logical combination from the separate sense amplifiers can be generated as an output of the unit cell.
