An in-memory compute (IMC) device includes an array of memory cells and control logic coupled to the array of memory cells. The array of memory cells is arranged as a plurality of rows of cells intersecting a plurality of columns of cells. The array of memory cells includes a first subset of memory cells forming a plurality of computational engines at intersections of rows and columns of the first subset of the array of memory cells. The array also includes a second subset of memory cells forming a plurality of bias engines. The control logic, in operation, generates control signals to control the array of memory cells to perform a plurality of IMC operations using the computational engines, store results of the plurality of IMC operations in memory cells of the array, and computationally combine results of the plurality of IMC operations with respective bias values using the bias engines.

The present disclosure is directed to a circuit layout of a dual port static random-access-memory (SRAM) cell. The memory cell includes active regions in a substrate, with polysilicon gate electrodes on the active regions to define transistors of the memory cell. The eight transistor (8T) memory cell layout includes a reduced aspect ratio and non-polysilicon bit line discharge path routing by positioning an active region for the first port opposite an active region for the second port and consolidating power line nodes at a central portion of the memory cell.
