International Classification:
G06F 12/00
US Classification:
711114
Abstract:
A method for improving performance of a digital memory array device including a plurality of memory cells; each respective memory cell storing a first digital value and a second digital value being an inverse of the first digital value; storing of the first and second digital values being controlled by a first digital signal effecting selection of a specified memory cell for storing; includes: (a) determining an extant value relating to the first digital signal; (b) if the extant value has a first value, effecting a bit flip operation in the specified memory cell to invert values of at least one of the stored first digital and the second digital values; (c) if the extant value does not have the first value, foregoing the bit flip operation in the specified memory cell.

Memory Cell Bit Valve Loss Detection And Restoration

US Patent:
7653846, Jan 26, 2010
Filed:
Dec 28, 2006
Appl. No.:
11/648490
Inventors:
Nam Sung Kim - Portland OR, US
Yibin Ye - Portland OR, US
Dinesh Somasekhar - Portland OR, US
Vivek De - Beaverton OR, US
Assignee:
Intel Corporation - Santa Clara CA
International Classification:
G11C 29/00
US Classification:
714718
Abstract:
For one embodiment, an apparatus may include a memory cell to store a bit value, wherein the memory cell may lose the bit value in response to a memory access operation. The apparatus may also include first circuitry to detect whether the memory cell loses the bit value in response to the memory access operation and second circuitry to restore the bit value in the memory cell in response to detection that the memory cell loses the bit value. Other embodiments include other apparatuses, methods, and systems.

Delay Fault Detection Using Latch With Error Sampling

US Patent:
7653850, Jan 26, 2010
Filed:
Jun 5, 2007
Appl. No.:
11/758124
Inventors:
James W. Tschanz - Portland OR, US
Keith A. Bowman - Hillsboro OR, US
Nam Sung Kim - Portland OR, US
Chris Wilkerson - Portland OR, US
Shih-Lien L. Lu - Portland OR, US
Tanay Karnik - Portland OR, US
Assignee:
Intel Corporation - Santa Clara CA
International Classification:
G01R 31/28, G06K 5/04
US Classification:
714726, 714699
Abstract:
Some embodiments provide sampling of a data signal output from a path stage using a latch, sampling of the data signal output from the path stage using an edge-triggered flip-flop, comparing a first value output by the latch with a second value output by the edge-triggered flip-flop, and generating an error signal if the first value is different from the second value.
