摘要： A decoder circuit, responsive to a burst sequence control signal, for accessing a memory location in a memory array. The decoder circuit receives an address signal and outputs a plurality of first select lines. Logic circuitry receives these first select lines and a burst sequence control signal and outputs a plurality of second select lines. When the bust sequence control signal is unasserted, the logic circuitry passes through to the plurality of second select lines the signals received on the plurality of first select lines. When the burst sequence control signal is asserted, the logic circuitry performs a logical operation on the signals received on the plurality of first select lines and outputs the result on the plurality of second select lines.

摘要： An apparatus and method for reducing power consumption within dynamic memory devices having internal self-refresh circuitry. The circuits for generating isolator control (ISO), pre-decoded row address (PXID) and/or word enable (WE) signals are configured in response to receipt of self-refresh and refresh counter signals to output different timing and sequencing when in self-refresh mode than when in normal mode of the memory device. Conventionally, ISO signals are controlled from a block selection circuit which also controls bit line equalization (BLEQ) and sense amplifier enable (SAPN). While in conventional circuits the PXID and WE signals are generated in response to the output of the address decoder and thus have a fixed timing in relation to the output of the address decoder. The use of different timing and sequencing can lower power consumption, such as by outputting fewer signal transitions per block during self-refresh.

摘要： Source transistor configurations are described for reducing leakage and delay within integrated circuits. Virtual power and ground nodes are supported with the use of stacked transistor configurations, such as a two transistor stack between a first virtual supply connection and VSS, and a second virtual supply connection and VDD. Gate drives of these stacked transistors are modulated with different voltage levels in response to the operating power mode of the circuit, for example active mode, active-standby mode, and deep power-down mode. Means for driving these source stacks are described. In one embodiment separate virtual nodes are adapted for different types of circuits, such as buffers, row address strobe, and column address strobe. Other techniques, such as directional placement of the transistors is also described.

摘要： Dynamic Random Access Memory (DRAM) circuits and methods are described for reducing leakage and increasing repaired yield. These objects are accomplished according to the invention by grouping refresh cycles within a single activation of power control, the use of limiting circuits or fuses to mitigate power losses associated with micro-bridging of bit-lines and word-lines, modulating the bit-line voltage at the end of precharge cycles, configuring refresh control circuits to use redundant word-lines in generating additional refresh cycles for redundant rows of memory cells, and combinations thereof. In one aspect, word-line fuses indicate modes of use as: unused, replacement, additional refresh, and replacement with additional refresh. The refresh control circuit utilizes these modes in combination with the X-address stored in the word-line fuses for controlling the generation of additional refresh cycles toward overcoming insufficient data retention intervals in select memory cell rows.

摘要： A CMOS constant voltage generator circuit having input and output stages and at least one compensation stage. Each stage can comprise a single transistor or more typically a transistor stack. Current mirroring is performed between the input stage and compensation stage, as well as preferably between the input stage and output stage. The compensation stage also provides additional biasing to a transistor in the output stage to increase voltage regulation. Optionally, degeneration resistors (passive or active) are coupled to the source side, drain side, or a combination of source and drain sides in the compensation and output stages. Optionally, additional diode-coupled transistors are incorporated in the transistor stack of the output stage. The circuit provides accurate voltage reference (Vref) output with lowered sensitivity to temperature and supply voltage.

摘要： A semiconductor memory device having a macro command function includes a macro storage section for storing a series of external instructions synchronized with a clock signal and a plurality of interval data corresponding to a number of clock pulses occurring between the external instructions. A counter is also included for counting the clock pulses and for producing an output representing a number of clock pulses occurring since an initialization of the counter, and a selecting section is included for selecting between a current external instruction synchronized with the clock signal and the external instructions read out from the macro storage section. A comparing section is included for comparing the interval data of the appropriate external instruction from the macro storage section with an output of the counter, and a macro control section is included for controlling the macro storage section in response to a macro store command so that the series of external instructions and the number of clock pulses counted by the counter are stored in the macro storage section. The macro control means also controlling the selecting section to select the macro storage section in response to a macro execute command so that the series of instructions stored in the macro storage section are sequentially read out. The macro control also produces a next command when the interval data of the read-out external instruction equals the output of the counter.
