Abstract

A chained memory IC in which a dual voltage scheme is used for operating the wordlines is described. During standby mode, the wordlines are maintained at a first logic 1 voltage level. To prepare for a memory access, the non-selected wordlines are driven to a boosted voltage while the selected wordline is driven to ground. The first logic 1 voltage level is less than the boosted voltage. This reduces the stress on the gate oxide of the transistors, thus improving reliability of the memory IC.
