20080319717 | EFFICIENT METHOD AND COMPUTER PROGRAM FOR MODELING AND IMPROVING STATIC MEMORY PERFORMANCE ACROSS PROCESS VARIATIONS AND ENVIRONMENTAL CONDITIONS - An efficient method and computer program for modeling and improving stating memory performance across process variations and environmental conditions provides a mechanism for raising the performance of memory arrays beyond present levels/yields. Statistical (Monte-Carlo) analyses of subsets of circuit parameters are performed for each of several memory performance variables and then sensitivities of each performance variable to each of the circuit parameters are determined. The memory cell design parameters and/or operating conditions of the memory cells are then adjusted in conformity with the sensitivities, resulting in improved memory yield and/or performance. Once a performance level is attained, the sensitivities can then be used to alter the probability distributions of the performance variables to achieve a higher yield. Multiple cell designs can be compared for performance, yield and sensitivity of performance variables to circuit parameters over particular environmental conditions in order to select the best cell design. | 12-25-2008 |
20140181762 | LITHOGRAPHY AWARE LEAKAGE ANALYSIS - A method for performing leakage analysis includes receiving information specifying an integrated circuit. A neighborhood of shapes associated with the integrated circuit is then determined Leakage information associated with the integrated circuit is generated based on the neighborhood of shapes. The neighborhood of shapes may be determined by determining a first set of spacings to a boundary of a first cell from an internal shape. A second set of spacings may be determined from the boundary of the first cell to a shape of a second cell. A lithography process may be characterized using the first and second set of spacings. | 06-26-2014 |

20160034205 | SYSTEMS AND/OR METHODS FOR LEVERAGING IN-MEMORY STORAGE IN CONNECTION WITH THE SHUFFLE PHASE OF MAPREDUCE - Certain example embodiments relate to a computer system for performing a map reduce sequence. Nodes therein include at least one processor and memory and are divided into at least mapper and reducer nodes. Each mapper node executes a map function on input to generate intermediate output elements. Each said intermediate output element includes a first key-value pair. Each element key includes associated map and reduce task identifiers. Each element value includes substantive data, organized as another key-value pair. The intermediate output elements are stored to memory. Each reducer node: retrieves at least intermediate output element values from the memory of a given mapper node, using specified map and reduce task identifiers; stores the retrieved element values to its memory; executes a reduce function on the retrieved element values, in order; and outputs a result from the reduce function for the map reduce sequence. Disk operations advantageously are reduced or eliminated. | 02-04-2016 |

20150270906 | Isolation of RF Signals using Optical Single Side Band Modulation Combined with Optical Filtering - A method and apparatus for isolating an RF signal are provided. A first RF signal is received and passed to an input of a 90 degree hybrid. An output of the 90 degree hybrid is connected to a first waveguide and a second output is connected to a second waveguide of an optical modulator. A second RF signal is received and passed to an input of a second 90 degree hybrid. An output of the second 90 degree hybrid is connected to the second waveguide and a second output is connected to the first waveguide of the optical modulator. The optical modulator is biased to produce single side band optical outputs of the RF signals. The single side band optical outputs are passed to an optical notch filter to remove one of the side band outputs. The other of the side band optical outputs is converted to an electrical signal. | 09-24-2015 |
