Patent ID: 10452972

Abstract:
A hardware implementation of a temporal memory system is disclosed. One aspect includes at least one array of memory cells logically organized in rows and columns, wherein each of the memory cells is adapted for storing a scalar value and adapted for changing the stored scalar value. The hardware implementation additionally includes an input system adapted for receiving an input frame as input and for creating a representation for the input, where the input comprises information for addressing the memory cells in the at least one array. The hardware implantation additionally includes at least one addressing unit for identifying a memory cell in the at least one array with a row address and a column address. The at least one addressing unit includes a column addressing unit for receiving the representation or a derivative thereof as input and applying the representation or the derivative as a column address to the array of memory cells, and a row addressing unit for receiving a delayed version of the representation at a specified time in the past as input, and applying this representation as a row address to the array of cells. The hardware implementation further includes a reading unit adapted for reading out scalar values from a selected row of memory cells in the array, based on the row address applied, wherein each scalar values read out by the reading unit corresponds to a likelihood of temporal coincidence between the input representation of the row address and the input representation of the column address, the likelihood being adjustable through the scalar value stored in the memory cell.
