Abstract: Circuits and methods for implementing a 10-T SRAM cell with independent read and write data ports, no data line precharge between cycles, and single-ended read and write access into the SRAM cell. The single ended nature of the cell and the elimination of a precharge period between accesses on both read and write ports saves considerable active power. This, in conjunction with the elimination of traditional column decode such that only the addressed SRAM cells are connected to their read or write data lines saves additional power while retaining reasonably high speeds, very good yield and enables the SRAM to operate in the voltage range that are near and below the threshold voltages of the MOSFET transistors.

Abstract: A catalytic filter is provided having a mixture of an SCR catalyst and soot oxidation catalyst where the soot oxidation catalyst is a copper doped ceria, iron doped ceria or manganese doped ceria. The mixture of an SCR catalyst and soot oxidation catalyst provides for a lowering of the peak oxidation temperature for soot removal from the filter.
