ALEXANDRIA, Va., Jan. 18 -- Freescale Semiconductor, Austin, Texas, has been assigned a patent (8,355,294) developed by Prakash Makwana, Noida, India, and Prabhjot Singh, Noida, India, for a "synchronous data processing system for reliable transfer of data irrespective of propagation delays and process, voltage and temperature (PVT) variations."
The abstract of the patent published by the U.S. Patent and Trademark Office states: "A synchronous data processing system includes a memory module to store data and a memory controller coupled to the memory module. The memory controller includes a clock inverter to receive an input clock signal and to transmit an inverted clock signal to the memory module. The inverted clock signal incurs a first propagation delay prior to reaching the memory module as a memory clock signal. A write data buffer is coupled to the memory module. The write data buffer transmits data to the memory module in response to the input clock signal. An asynchronous first-in-first-out (ASYNC FIFO) buffer is coupled to the memory module. The ASYNC FIFO buffer reads data from the memory module in response to a feedback signal generated by feeding back the memory clock signal to the ASYNC FIFO buffer."
The patent application was filed on March 18, 2011 (13/050,932). The full-text of the patent can be found at http://patft.uspto.gov/netacgi/nph-Parser Sect1=PTO2&Sect2=HITOFF&p=1&u=%2Fnetahtml%2FPTO%2Fsearch-bool.html&r=1&f=G&l=50&co1=AND&d=PTXT&s1=8,355,294&OS=8,355,294&RS=8,355,294
