US Patent 11256503 Computational memory

A processing device includes an array of processing elements, each processing element including an arithmetic logic unit to perform an operation. The processing device further includes interconnections among the array of processing elements to provide direct communication among neighboring processing elements of the array of processing elements. A processing element of the array of processing elements may be connected to a first neighbor processing element that is immediately adjacent the processing element. The processing element may be further connected to a second neighbor processing element that is immediately adjacent the first neighbor processing element. A processing element of the array of processing elements may be connected to a neighbor processing element via an input selector to selectively take output of the neighbor processing element as input to the processing element. A computing device may include such processing devices in an arrangement of banks.
