Parallel Test In Asynchronous Memory With Single-Ended Output Path

US Patent:
6662315, Dec 9, 2003
Filed:
Nov 26, 2002
Appl. No.:
10/305699
Inventors:
Iulian C. Gradinariu - Colorado Springs CO
John J. Silver - Monument CO
Keith A. Ford - Colorado Springs CO
Sean B. Mulholland - Colorado Springs CO
Assignee:
Cypress Semiconductor Corporation - San Jose CA
International Classification:
G06F 1100
US Classification:
714 42
Abstract:
An asynchronous memory device includes parallel test circuitry configured to interface with a single-ended output data path of the memory device and, in some cases, to provide a measure of a slowest cell access time for the memory device. The parallel test circuitry may include first circuitry configured to receive logic signals from a plurality of cells of the memory device and to provide first output signals indicative of logic states of the plurality of cells; and second circuitry configured to receive the first output signals and to produce a second output signal indicative of the logic states of the first output signals therefrom. For example, the first circuitry and the second circuitry may be configured as a wired NAND and wired NOR combination. In some cases, one or more of the cells may be included within a redundant row or column of the memory device. The first circuitry may include one or more circuits, each including an input path from a first number of the plurality of cells and configured to provide at least one of the first output signals.

Block Redundancy In Ultra Low Power Memory Circuits

US Patent:
6535437, Mar 18, 2003
Filed:
Jun 15, 2001
Appl. No.:
09/882898
Inventors:
John J. Silver - Monument CO
Iulian C. Gradinariu - Colorado Springs CO
Bogdan I. Georgescu - Colorado Springs CO
Keith A. Ford - Colorado Springs CO
Sean B. Mulholland - Colorado Springs CO
Danny L. Rose - Monument CO
Assignee:
Cypress Semiconductor Corp. - San Jose CA
International Classification:
G11C 700
US Classification:
365200, 365226, 365227
Abstract:
A circuit comprising a memory array and a logic circuit. The memory array may be configured to read or write data in response to (i) one or more enable signals and (ii) one or more control signals. The logic circuit may be configured to generate the enable signals in response to one or more address signals. De-assertion of one or more of the enable signals generally reduces current consumption in the memory array.

Parallel Test For Asynchronous Memory

US Patent:
6324107, Nov 27, 2001
Filed:
Aug 15, 2000
Appl. No.:
9/639454
Inventors:
James D. Allan - Colorado Springs CO
John J. Silver - Colorado Springs CO
Keith A. Ford - Colorado Springs CO
Assignee:
Cypress Semiconductor Corporation - San Jose CA
International Classification:
G11C 700
US Classification:
365201
Abstract:
An asynchronous memory device includes parallel test circuitry configured to provide a measure of a slowest bit access time for the device. The parallel test circuitry may include first circuitry configured to receive logic signals from a plurality of cells of the device and to provide first output signals indicative of logic states of the plurality of cells. The parallel test circuitry may also include second circuitry configured to receive the first output signals and to produce second output signals indicative of logic states of the first output signals therefrom. The parallel test circuitry may be the same circuitry used in the read path of the memory device, and may be configured such that the second output signals are produced at the slowest bit access time. The plurality of cells tested may include a redundant cell of the device. Such redundancy is transparent to the test circuitry.

US Patent:
5675542, Oct 7, 1997
Filed:
Jun 28, 1996
Appl. No.:
8/671671
Inventors:
Keith A. Ford - Colorado Springs CO
Assignee:
Cypress Semiconductor Corp. - San Jose CA
International Classification:
G11C 700, G11C 702

Abstract:
A method and apparatus for reducing noise in a memory bit-line pull-up circuit. The memory bit-line pull-up circuit includes a first reference line, a second reference line, a first capacitor, a gating device, and a pull-down circuit. The circuit may further include a load transistor coupled between the first reference line and a first voltage conduit, which generally maintains the voltage on the first reference line at Vcc-Vt, and a second capacitor and the load transistor providing a pull-up path for the voltage on the first reference line when Vcc increases and the first capacitor. The pull-down circuit provides a pull-down path for the voltage on the first reference line when Vcc decreases. The first capacitor provides a pull-up path for the voltage on the second reference line. A first gating device couples a bit-line to the first reference line.
