Abstract
A device for implementing sparse distributed memory may include first circuitry having a plurality of cells arranged in first subsets. The first circuitry may be configured to receive a first input vector for a write operation and calculate a similarity between the first subsets of the first circuitry and the first input vector. The device may include second circuitry coupled to the first circuitry and configured to output a first activation signal. The device may include third circuitry coupled to the second circuitry and having cells arranged in second subsets. The third circuitry may be configured to receive the first activation signal and selectively activate one or more first selected subsets of the second subsets in response to the first activation signal by incrementing or decrementing corresponding values of the cells of the one or more first selected subsets based on the first input vector.
