This document describes a spatial light modulator that comprises a pixel array having a plurality of pixels whereby each pixel in this array is communicatively coupled to a digital pixel circuit which are in turn all coupled to a bit-plane control circuit. The bit-plane control circuit is configured to generate, using a Pulse Code Modulation (PCM) algorithm, bit-plane signals that are used to control the sample and hold functions performed by each of the digital pixel circuits so that the pixel array may carry out its scanning function accurately and in a power efficient manner.

Spatial light modulator

Various embodiments may provide a circuit arrangement. The circuit arrangement may include a first spin-orbit torque magnetic tunnel junction cell, a second spin-orbit torque magnetic tunnel junction cell, a first driver circuit arrangement, a second driver circuit arrangement, and a read circuit arrangement. The circuit arrangement allows for the operation of a non-volatile flip-flop based on spin-orbit torque effect.

According to embodiments of the present invention, a writing circuit for a magnetoresistive memory cell is provided. The writing circuit includes a first connecting terminal configured to provide a first electrical signal to switch a variable magnetization orientation of the free magnetic layer from a first magnetization orientation to a second magnetization orientation; a second connecting terminal configured to provide a second electrical signal to switch the magnetization orientation from the second magnetization orientation to the first magnetization orientation; and a sourcing switch configured to provide for a write operation a connection of the first or second connecting terminal to a node coupleable to the magnetoresistive memory cell. The first and second electrical signals have different amplitudes, and the first and second electrical signals are of the same polarity. Further embodiments relate to a memory cell arrangement and a method of writing into a target magnetoresistive memory cell.
