    摘要: A multi-port memory cell (200) can be formed from seven transistors. Single ended write operations can be performed without a boosted word line voltage or variable power supply. A data value (D/DB) stored in the memory cell (200) can be cleared by shorting complementary data nodes (204-0 and 204-1) together. Write data can then be placed on a bit line. Complementary data nodes (204-0 and 204-1) can then be isolated once again, resulting in the write data being latched within the memory cell (300). An access method (700) for a multi-port memory cell is also described.

    摘要: A power-on reset control circuit and associated method for deactivating a global power-on-reset signal based on whether circuitry, critical to correct functionality of an electronic system employing the power-on reset, is functioning correctly. The power-on reset control circuit comprises a control emulation circuit for transmitting a control signal through a first control line to indicate that the circuitry is operating correctly. The power-on reset control circuit further comprises a control verification circuit, coupled to the control emulation circuit through the first control line, for deactivating the global power-on reset signal upon receiving an active local power-on reset signal indicating that the power source is providing a voltage at an operating threshold level and the active control signal from the control emulation circuit.

    摘要: A variable impedance sense (VIS) circuit (600) can detect and store an input offset value inherent in a sensing loop (620 and/or 622). According to a detected input offset polarity, a resulting impedance matching binary code can be adjusted to compensate for error that can be introduced by the input offset. The binary code can also be adjusted to compensate for additional error that can be introduced by dropping a least significant bit (LSB) of the code to reduce noise effects caused by the switching of the LSB.
