ABSTRACT:
A liquid crystal memory device comprising a liquid crystal layer, means for preconditioning the layer so that at least some of its molecules will be slanted towards one of two possible tilt directions, means for causing at least some of the molecules of said liquid crystal layer to assume their preconditioned tilt direction, and means for determining which of said possible tilt directions has been assumed by the molecules of said liquid crystal layer is disclosed. The method of writing into this device comprises causing the molecules of selected portions of said liquid crystal layer to be preconditioned to slant towards one of two possible tilt directions, causing at least some of said preconditioned molcules to assume their preconditioned tilt direction, causing at least some of the molecules of other portions of said liquid crystal layer to be preconditioned to slant towards the other one of said two possible tilt directions, and causing at least some of said preconditioned molecules to assume their other preconditioned tilt direction.
