Abstract
Systems, methods, and devices that employ deterministic programming techniques to facilitate efficient programming of memory elements in a memory are presented. A memory component comprises an optimized program component that can divide a group of memory elements selected for programming into a desired number of subgroups based in part on respective current threshold voltage levels (Vt) of the memory elements; apply respective program pulses to each memory element in respective subgroups; measure respective Vt levels of memory elements after the pulse; and verify as passed memory elements that meet a target Vt. The optimized program component can divide a subset of memory elements that do not meet the target Vt into a desired number of subgroups based in part on respective current Vt levels of the memory elements and can continue to perform this deterministic programming process until all memory elements are verified as passing for the target Vt.
