20090132849Method and Computer Program for Selecting Circuit Repairs Using Redundant Elements with Consideration of Aging Effects - A method and computer program for selecting circuit repairs using redundant elements with consideration of aging effects provides a mechanism for raising short-term and long-term performance of memory arrays beyond present levels/yields. Available redundant elements are used as replacements for selected elements in the array. The elements for replacement are selected by BOL (beginning-of-life) testing at a selected operating point that maximizes the end-of-life (EOL) yield distribution as among a set of operating points at which post-repair yield requirements are met at beginning-of-life (BOL). The selected operating point is therefore the “best” operating point to improve yield at EOL for a desired range of operating points or maximize the EOL operating range. For a given BOL repair operating point, the yield at EOL is computed. The operating point having the best yield at EOL is selected and testing is performed at that operating point to select repairs.05-21-2009

20090271669High-Speed Testing of Integrated Devices - A method for allowing high-speed testability of a memory device having a core with memory cells for storing data, comprising: enabling a data signal having a first logical state or a second logical state from the core to reach an output port of the memory device within an evaluate cycle during a functional operating mode and pass an array built in self test during LBIST mode; enabling the data signal to change from the first logical state to the second logical state during LBIST mode at a time that coincides with the latest possible time the data signal from the core can reach the read output port within the evaluate cycle during the functional operating mode and pass the array built in self test; and executing a logic built-in self test configured to test a logic block located downstream of a transmission path of the memory device.10-29-2009
20100039876Functional Float Mode Screen to Test for Leakage Defects on SRAM Bitlines - A method and system for maintaining Static Random Access Memory (SRAM) functionality while simultaneously screening for leakage paths from bitline to ground during Float Mode operation. The SRAM configuration enables SRAM cell selection for a read or write operation. In response to the SRAM cell selection, a group of pre-charge (PCHG) signals are provided with a high value. When selection is made from a top sub-group of SRAM cells, a corresponding bitline, “BLT_TOP”, takes a value which reflects a state stored in the selected cell. In addition, the bitline corresponding to the bottom sub-group of cells, “BLT_BOT”, takes a high value. If there is a leakage defect, BLT_BOT drops to a low value. With no leakage defect, the data stored in the selected cell is determined based on the result of a logical NAND operation including the respective states indicated by the BLT_TOP and by the BLT_BOT.02-18-2010
20100195408Non-Body Contacted Sense Amplifier with Negligible History Effect - In a method of mitigating hysteresis effect in a sense amplifier circuit, a data value is sensed from a data source with the sense amplifier during a first period. The data value is stored in a latch. The data valued stored in the latch is inverted, thereby generating an inverted data value. The data source is isolated from the sense amplifier and the inverted data value is read with the sense amplifier during a second period immediately following the first period.08-05-2010

20080231299Vacuum chamber with two-stage longitudinal translation for circuit board testing - A circuit board tester that uses a dual-stage translation to bring a unit under test (UUT) into physical and electric contact first with a series of tall probes, then with a series of short probes. Initially, the UUT is mounted on a support plate, and spaced apart from both the tall and short probes. First, in order to perform a functional test on the UUT, a first vacuum stage is engaged, and atmospheric pressure translates the UUT longitudinally until contact is made with a first hard stop, defining a first position. At this first position, the UUT is in contact with a series of tall probes, and is spaced apart from a series of short probes. After a function test is performed, a second vacuum stage is engaged in addition to, and independent of, the first vacuum stage. Atmospheric pressure translates the UUT longitudinally until contact is made with a second hard stop, defining a second position.09-25-2008
