An input buffer system has an input clipping circuit. The input clipping circuit has a high voltage input and uses transistors all being the thin oxide type transistors. A high voltage detect circuit is coupled to the input clipping circuit. An input buffer circuit is coupled to the input clipping circuit and has a low voltage output range.

A circuit comprising a sense amplifier, an evaluation circuit, a control circuit and a register circuit. The sense amplifier circuit may be configured to present a first output and a second output in response to (i) an input signal and (ii) an enable signal.

The control circuit may be configured to present (i) a first clock signal, a second clock signal and an enable signal in response to (i) the evaluation signal and (ii) a wordline signal. The register circuit may be configured to hold either the first or second output in response to the first and second clock signals. The register circuit may be implemented as a master-slave register that may respond to the first and second clock signals.

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.

An apparatus comprising a first compare circuit, a second compare circuit and a memory. The first compare circuit may be configured to present a first match signal in response to a first address and a second address. The second compare circuit may be configured to present a second match signal in response to the first match signal, a first write enable signal and a second write enable signal. The memory may also be configured to present the first and second write enable signals. In one example, the memory may be configured to store and retrieve data with zero waiting cycles in response to the second match signal.

The present invention concerns a method and apparatus for disabling columns using a local fuse decoding system. The present invention uses local decoding in order to use a number of fuses that is less than the number of columns in order to disable column failures. This is particularly useful when the fuse pitch is greater than the column pitch which does not allow for a fuse to be implemented in each column.
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.
