Abstract

A device and method for storing information including an array of memory cells organized in bitlines and wordlines. The bitlines are subdivided in sections of wordlines and the sectioned bitlines are connected to a global bitline by a connector. The connector is made bidirectional and uses the high order part of the wordline addresses for this section of bitlines as a disable reset command. The reset stays active for unselected portions, compensating leakage of a mass of unselected cells which could disturb valid read signals.
