Abstract
An Organic-Like Memory (OLM), i.e., one in which information already in storage is enhanced or degraded with each new access. The OLM typically consists of a conventional random access memory (RAM) embedded in an analog computer. The data D (typically a number of bits) already stored at a given address A in the RAM is modified rather than simply re-written every time a stimulus or other item of information S is entered in the OLM. When an item of information S is to be entered in OLM at address A, the following takes place: information S is multiplied by a weight factor W, yielding a first product; information D is read from RAM address A and multiplied by a quality factor Q, yielding a second product; the two products are added, and the result stored back at address A. The source and time of sampling of S, address A, weight factor W and quality factor Q are determined by a separate control circuit, in which the appropiate program can typically be loaded. Data in RAM can also be read in a conventional way.
