Abstract
A memory circuit, including a memory array (such as a cross-point array), may include circuit elements that may function both as selection elements/drivers and de-selection elements/drivers. A selection/de-selection driver may be used to provide both a selection function as well as an operation function. The operation function may include providing sufficient currents and voltages for WRITE and/or READ operations in the memory array. When the de-selection path is used for providing the operation function, highly efficient cross-point implementations can be achieved. The operation function may be accomplished by circuit manipulation of a de-selection supply and/or de-selection elements.
