    摘要: A peak current modeling method and system for modeling peak current demand of an integrated circuit (IC) block such as, e.g., a compilable memory instance. A current demand curve associated with the IC for a particular IC block event is obtained via simulation, for example. A defined time region associated with the particular IC block event is divided into multiple time segments, whereupon at least a first current value and a second current value for each time segment is obtained based on the current demand curve. Thereafter, the current demand curve is approximated, on a segment-by-segment basis, using a select approximate waveform depending on a relationship between the first and second current values.

    摘要: Power supply regulation. A power supply regulation system includes a transistor through which power is carried. The system also includes a switch connected to a gate of the transistor. Further, the system includes a transmission gate responsive to an input signal to apply a first signal level causing the transistor to enter an ON state in which the transistor carries full power, to apply a second signal level causing the transistor to enter an OFF state in which the transistor carries no power and to apply a third signal level causing the transistor to enter an INTERMEDIATE state in which the amount of power the transistor carries is controlled by the switch.

    摘要: A method and system for storing secure data in a multi-time programmable, non-volatile electrically-alterable memory device are disclosed. Accordingly, in an embodiment, a memory device may include a data register with a fixed N-bit pattern, comparator logic, control logic, and an array of non-volatile electrically-alterable memory cells. Each memory cell includes a floating gate to store an electronic charge representing the logical state of the memory cell. The plurality of memory cells may be logically partitioned to include an N-bit secure lock and a plurality of memory cells for storing secure data. The random bit values stored in the N-bit secure lock are read, and compared with the fixed N-bit pattern stored in the data register. If the N-bit patterns do not match, the control logic allows the plurality of memory cells for storing secure data to be programmed with secure data.

The memory has a plurality of memory cells organized into groups of memory cells. The noise reduction circuit performs a sense operation on a first group of memory cells at the substantially the same time. The noise reduction circuit performs a sense operation on a second group of memory cells at substantially the same time. The noise reduction circuit has timing circuitry to sense the second group of memory cells after the sense of the first group initiates but prior to the completion of the sense operation on the first group of memory cells.
