Abstract

An integrated circuit includes, in one example, an active memory cell array and a passive variable resistance memory cell array positioned above the active memory cell array, such as in upper layers of the integrated circuit. The active memory cell array and the passive variable resistance memory cell array share one or more components of memory control logic such as address decode logic, data read logic and/or data write logic. As such, a type of active memory and passive variable resistance memory hybrid structure shares memory control logic such as word line drivers, bit line drivers and read logic. The active memory cell array and passive variable resistance memory cell array overlap reducing integrated circuit die size, improving power reduction and reducing costs by sharing peripheral circuits.
