Correction of corrupted elements in sensors using analog/multi-level non-volatile memory

Abstract

A method and system using a sensor array includes a programmable analog/multi-level memory array for modifying individual outputs from elements in the sensor array in order to obtain a desired sensor array output. The memory array can be programmed with data corresponding to desired modifications, such as low and high offset voltage correction, low gain correction, and gamma correction. Consequently, by utilizing arithmetic circuits, the adverse effects of corrupted elements in a sensor can be corrected by re-programming the memory array with different modification data as the need arises.
