Patent number: 7944760Abstract: An electronic circuitry is provided for reading out a memory element (ME). The electronic circuitry comprises a first electronic path (IP) being coupled to the memory element (ME), a second electronic path (RP) having predetermined electrical properties, and a basic detection element (BDE) being coupled to the first and second electronic paths (IP, RP) such that the information contained in the memory element (ME) can be determined by the basic detection element (BDE) based on the relation of a digital signal being propagated over the first path (IP) to a digital signal being propagated over the second path (RP).Type: GrantFiled: October 29, 2007Date of Patent: May 17, 2011Assignee: NXP B.V.Inventor: Cedric Mayor

Publication number: 20100283051Abstract: The present invention relates to a monitor cell (200) for monitoring local variations in a process parameter of an integrated circuit. The monitor cell (200) comprises a first delay path (220) located in a first area (100, 110, 120) of the integrated circuit and a second delay path (230) located in a second area (100, 110, 120) of the integrated circuit. The first delay path (220) is faster than the second delay path (230) when the difference in the respective process parameter values of the first area and the second area is smaller than a predefined threshold. In contrast, the second delay path (230) is faster than the first delay path (220) when said difference is larger than the predefined threshold. The monitor cell further comprises an input (210) arranged to provide the first delay path (220) and the second delay path (230) with a test signal (260) and a signal detector (240) for detecting the order in which the delay paths (210; 220) output the test signal (260).Type: ApplicationFiled: December 29, 2008Publication date: November 11, 2010Applicant: NXP B.V.Inventor: Cedric Mayor

Patent number: 7706172Abstract: A SRAM memory cell including two inverters and a plurality of switches is provided. The SRAM cell is manufactured in a technology offering N/P shunt capabilities and the inputs of the inverters are connected to at least one pair of bit lines (BLa, BLa/; BLb, BLb/) via two of the switches. The switches are controlled by a signal word line (WLa, WLb). Each inverter includes a first transistor (MN0, MN1) of a first conductivity type and a second transistor (MP0, MP1) of a second conductivity type. Each switch includes at least a third transistor (MN2, MN3) of the first conductivity type, characterized in that the two transistors (MP0, MP1) of the second conductivity type in the inverters are arranged in two opposite end regions of the memory cell, respectively.Type: GrantFiled: March 25, 2005Date of Patent: April 27, 2010Assignee: Arm LimitedInventors: Cedric Mayor, Denis Dufourt
