36results about How to "Improve skew" patented technology

Fully-buffered dual in-line memory modules (FB-DIMM) include advanced memory buffers (AMBs) having enhanced skew, slew rate and output impedance control. The AMB includes user accessible registers that can be programmed to carefully control the edge placement (or phase) of signals generated from the AMB to multiple DRAMs on the module. This control of edge placement, which may be performed independently for each group of signals: clock (CLK, CLK#), command (RAS, CAS, WE), address (including bank address), data (DQ) and data strobe (DQS), provides 360 degrees of control (or one period). This means that any group of signals can be moved independently by one complete period relatively to any other group.

Physically unclonable function (PUF) memory employing static random access memory (SRAM) bit cells enhanced by stress for increased PUF output reproducibility. Stress voltage applied to SRAM bit cells enhances their skew so that the SRAM bit cells output their preferred initial state in subsequent PUF read operations regardless of process variation and other external environmental variations, such as temperature. The application of stress voltage on the SRAM bit cells in a PUF memory array takes advantage of the recognition of aging effect in transistors, where turning transistors on and off over time can increase threshold voltage resulting in lower drive current. Stress voltage can be applied to the SRAM bit cells to bias their threshold voltage to simulate this aging effect to enhance mismatch between transistors in the SRAM bit cell to more fully skew the SRAM bit cells for increased PUF output reproducibility with less susceptible to noise.
