This paper presents detailed simulation results on a modified Sparse Distributed Memory (SDM) system.We have modified Kanerva's original SDM system into an architecture with a ternary memory space.This enables the memory to be used as a Transient Episodic Memory (TEM) in cognitive software agents.TEM is a memory with high specificity and low retention, used for events having features of a particular time and place.Our earlier work focused on perfunctory, proof of concept assessments on the modified SDM system.This paper presents a detailed experimental evaluation of the modified SDM system with regard to its ability to store and retrieve episodic information.
