Abstract: A domino static random access memory (SRAM) having one or more SRAM memory cells connected with a local bit line is disclosed. The SRAM may include a precharge device connected between a voltage supply and the local bit line, and global bit line (GBL) discharge logic connected between a local bit line and a GBL. The GBL discharge logic transfers a logic value of the local bit line to the GBL during a read operation. GBL precharge logic connects the GBL to a global precharge input. The GBL precharge logic is adapted to draw the GBL to a precharge voltage above a discharge voltage and below a supply voltage during a precharge operation.

Abstract: A circuit and method erase at power-up all data stored in a DRAM chip for increased data security. All the DRAM memory cells are erased by turning on the transistors for the DRAM storage cells simultaneously by increasing the body voltage of cells. In the example circuit, the body voltage is increased by a charge pump controlled by a power-on-reset (POR) signal applying a voltage to the p-well of the memory cells. The added voltage to the p-well lowers the threshold voltage of the cell, such that the NFET transistor of the memory cell will turn on. With all the devices turned on, the data stored in the memory cells is erased as the voltage of all the cells connected to a common bitline coalesce to a single value.

For critical hold time paths, circuit devices in the critical hold time paths are placed on a single mask of either the first mask or the second mask. For critical setup time paths, path delays are reduced by providing a mixture of circuit devices on the first mask and the second mask.

Abstract: A semiconductor chip has an SRAM (static random access memory). The SRAM includes a data dependent write assist circuit which, on writes, reduces a supply voltage on one of a cross coupled inverter pair in an SRAM cell, thereby making it easier to overcome the one of the cross coupled inverters.

Abstract: A semiconductor chip has shapes on a particular level that are small enough to require a first mask and a second mask, the first mask and the second mask used in separate exposures during processing. A circuit on the semiconductor chip requires close tracking between a first and a second FET (field effect transistor). For example, the particular level may be a gate shape level. Separate exposures of gate shapes using the first mask and the second mask will result in poorer FET tracking (e.g., gate length, threshold voltage) than for FETs having gate shapes defined by only the first mask. FET tracking is selectively improved by laying out a circuit such that selective FETs are defined by the first mask. In particular, static random access memory (SRAM) design benefits from close tracking of six or more FETs in an SRAM cell.

Abstract: An insulin pump having an expected bolus interval and an early bolus interval. The early bolus interval immediately precedes the expected bolus interval. The insulin pump alerts the user if no bolus is taken during an expected bolus interval unless a bolus was taken during the early bolus interval. The insulin pump queries the user if the bolus taken during the early bolus interval is to be interpreted as satisfying the expected bolus interval; if so, no alert is given if no bolus is then taken during the expected bolus interval; if not, an alert is given if no bolus is taken during the expected bolus interval.

Abstract: Measurement of the period of a relatively slow but precise reference clock in terms of a high speed oscillating clock, such as from a voltage controlled oscillator (VCO). The reference clock is known to be accurate and stable and values of the time measurement unit are output that determine the integer and fractional number of the high speed oscillating clock periods which occurred during one reference clock cycle. The measurements are very accurate and all cycles of the reference clock are measured. Such measurements enable various frequency control schemes over the high speed oscillating clock source.
