Minnesota Inventor Develops Memory Accessing System

ALEXANDRIA, Va., May 9 -- Paul S. Neuman of Shoreview, Minn., has developed a memory accessing method.

According to the U.S. Patent & Trademark Office: "A system and method for dynamically accessing memory under normal operating conditions without interrupting computer system clocks that are otherwise executing. At least a memory access mode and a memory address(es) are scanned into a control scan chain from a maintenance system. When the scan is complete, the information is collectively transferred to an access register bank. Based on the control signals, a selection multiplexer selects the information from the control scan chain provided by the maintenance system as opposed to standard signals generated by the computer system. Memory control input signals are generated in response to a clock trigger signal, and the read or write data transfer is initiated."

The inventor was issued U.S. Patent No. 7,363,440 on April 22.

The patent has been assigned to Unisys Corp., Blue Bell, Pa.

The original application was filed on Dec. 30, 2004, and is available at: http://patft.uspto.gov/netacgi/nph-Parser?Sect1=PTO1&Sect2=HITOFF&d=PALL&p=1&u=%2Fnetahtml%2FPTO%2Fsrchnum.htm&r=1&f=G&l=50&s1=7,363,440.PN.&OS=PN/7,363,440&RS=PN/7,363,440.
