CONTACT LAYER TRACES TO PROGRAM PROGRAMMABLE ROM
A device includes a programmable ROM circuit, an address circuit, and a processor. The programmable ROM circuit includes multiple physically contiguous pairs of bit-cells, each pair of bit-cells includes an active layer trace extending continuously across both of the bit-cells, each pair of bit-cells comprises a shared contact layer point when the pair of bit-cells is programmed to a value of one and no shared contact layer point when the pair of bit-cells is programmed to a value of zero. The address circuit is coupled to the programmable ROM circuit and configured to address only a first bit-cell of each pair of bit-cells. The processor is coupled to the address circuit and the programmable ROM circuit and configured to use the address circuit to read data from one or more pairs of bit-cells of the programmable ROM circuit.
Array of integrated pixel and memory cells for deep in-sensor, in-memory computing
Disclosed are embodiments of an integrated circuit structure (e.g., a processing chip), which includes an array of integrated pixel and memory cells configured for deep in-sensor, in-memory computing (e.g., of neural networks). Each cell incorporates a memory structure (e.g., DRAM structure or a ROM structure) with a storage node, which stores a first data value (e.g., a binary weight value), and a sensor connected to a sense node, which outputs a second data value (e.g., an analog input value). Each cell is selectively operable in a functional computing mode during which the voltage level on a bit line is adjusted as a function of both the first data value and the second data value. Each cell is further selectively operable in a storage node read mode. Furthermore, depending upon the type of memory structure (e.g., a DRAM structure), each cell is selectively operable in a storage node write mode.
