    摘要: The present invention concerns data transition method and apparatus for driving a set of write data signals to an inactive (or deasserted) state upon completion of a WRITE to a particular group of memory cells. The present invention drives the write data signals to a an inactive state to end a WRITE without waiting for the end of the write control pulse. The present invention triggers a group of data write buffers to drive one of the write data signals to a "0" at the beginning of the WRITE control pulse or at a data input transition during a WRITE. A delayed transition of the write data signals may be used to drive both the write data signals to a "1"� to end the WRITE within a particular memory group. The write data transition detection is accomplished at the write data inputs of the groups of memory cells without relying on global chip data input pin transition detection and pulse width setting. The data setup to the end of WRITE is generally not compromised since the path from chip data input to the input to the write data signals is generally similar to existing implementations.

    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: The present invention concerns a method and apparatus for providing a dual level wordline clamp for use in a memory array. During a write operation, the clamp is at a level that ensures that a proper write margin is maintained. During a read operation, the clamp produces a lower level that reduces the overall current consumption of the circuit. During a write operation, the clamp also reduces the overall current consumption of the circuit. The present invention does not require complex reference circuits and, as a result, presents a minimal impact on die size.
