    摘要: A semiconductor memory chip architecture is described in which implementation of a multi-bit data control function which enables independent control of at least a plurality of data bits via a single control signal. A logically organized memory chip is organized as a 2 n X4 chip in which one control (CAS0) signal enables a single data bit and another control (CAS1) signal enables the remaining three data bits. By organizing data control on chips in this manner, it becomes possible to optimize design modules such that a minimum number of control signals are used.

    摘要: An integrated boost and local word line drive system that enhances the speed of the word line drive without providing excessive voltage stresses to the driver devices. A charge reservoir (20) stores a boost voltage (BST) under the control of a charge pump (15) that is regulated by a voltage regulator (10). One of the local word lines (LWL) coupled to a selected master word line (MWL) is enabled by a driver (50) that receives the boost voltage (BST). The switching times and signal slew rates of the driver, as well as the boost voltage, are controlled to prevent excessive gate stresses in the support circuitry.

    摘要: A programmable storage element for redundancy-programming includes a programmable antifuse circuit which includes a plurality of first resistors (F1a, F1b, F1c) and a switching circuit (Q Fa , Q Fb , Q Fc , Q Fd ) for coupling the first resistors in series in response to a plurality of first control signals (Ta, Tb, Tc, Td) and for coupling the first resistors in parallel in response to a plurality of second control signals to permit programming of the first resistors, and a sensing circuit for determining whether or not the first resistors have been programmed. The state of the first resistors is determined by comparing a first voltage drop across the first resistors with a second voltage drop across a second resistor. Each of the first resistors is an unsilicided polysilicon conductor which has an irreversible resistance decrease when a predetermined threshold current is applied for a minimum period of time.

    摘要: A fuse, having reduced blow-current requirements thereby minimizing the power supply voltage and chip area required for the driver transistors, has a geometry which is characterized by an essentially uniform width dimension throughout the primary axis of the fuse link but having at least one approximately right angle bend in the fuse link. The fuse can be blown open with approximately 10% of the input current density required for a straight fuse of equal cross-sectional area. The reason for this is that, due to current crowding, the current density is accentuated at the inside corner of the bend. As the input current to the fuse is increased, a current density is reached at the inside corner which causes the fuse material to melt. A notch forms at the inside corner. The fuse geometry altered by the notching causes even more severe current crowding at the notches, and this in turn makes the melting propagate across the width of the fuse. The predictability of the point of fuse blow out allows even greater circuit densities while minimizing the possibility of accidental damage to adjacent devices.

    摘要: A voltage reference circuit that produces an output offset from a supply voltage by approximately two volts, the output (VOUT) being relatively stable in the face of vacillations in the external power supplies. The first leg of the circuit utilizes devices (TPH1, TP1, TN1) having differing Vt's to produce an internal reference of one volt below Vdd. In a first embodiment of the invention, the second leg has a first device (TP2), wherein the gate receives the internal reference and the source is at the high power supply (VDD), and a high Vt diode connected device (TPH2). The two devices (TP2, TPH2) are matched to have the same overdrive current, which is at a voltage that is a function of the difference between the gate-to-source voltage of the first device and the threshold voltage of the first device. Thus, the output is a function of the overdrive to, and the diode drop across, the second high-Vt device.
