Abstract

See full text

A packet generator that increases the output speed of column and row addresses and data provided by a semiconductor device test system. The packet generator receives column and row addresses and data from a conventional algorithmic pattern generator (APG) and generates column and row addresses and data in packet form, thereby allowing communications with a packet-based device under test, such as a memory. The packet generator further provides variable time spacing between column and row addresses and data packets. Thereby, the packet generator advantageously allows testing of memory devices that require signal inputs at a higher rate than a conventional APG can provide.
