摘要： The present invention provides for evaluating a programmable anti-fuse element. For a programmable transistor anti-fuse, the gate of the anti-fuse is precharged with a predetermined voltage and/or current and the anti-fuse is subsequently evaluated. In one embodiment a precharge voltage sufficient to turn ON a transistor is provided to the gate. Here, an intact (unblown) transistor remains ON over a period of time and a damaged (blown) transistor dissipates the charge voltage and turns OFF. The status of the transistor is subsequently determined by evaluating the resistance between the drain and source. A high resistance indicates a blown condition and a low resistance indicates an unblown condition. In another embodiment, a small current is provided to the gate in which the small current is greater than a leakage current for an intact transistor and is less than a leakage current for a damaged transistor. An intact transistor charges to an ON state over a period of time but a damaged transistor does not because it's leakage current is greater than the small current provided to the gate. Again, the status of the transistor anti-fuse is subsequently determined by evaluating the resistance between the drain and source.

摘要： An anti-fuse system composed of a multiplicity of anti-fuse circuits (24, 26, 28, N) connected across a voltage source (10) by a pair of conductors (16, 18). Each anti-fuse circuit comprising an anti-fuse (30) connected in a series with a blow or control transistor (36) and a control circuit (44) for monitoring the status of the anti-fuse (30), Control circuit (44) provides an “on” signal to the gate (38) of control transistor (36) only when a_“select_” signal is received at an input (46) of control circuit (44) and if anti-fuse (30) has not been blown. After the anti-fuse (30) is blown, control circuit (44) turns off the control transistor (36) thereby providing a constant power source voltage across each anti-fuse circuit (24, 26, 28, N) regardless of the number of parallel anti-fuses which have been blown.

摘要： A sense amplifier for use with a dynamic random access memory is formed in a silicon integrated circuit. The pitch of an array of such sense amplifiers is equal to the pitch of pairs of bit lines of a memory array. Each array of sense amplifiers is formed from four rows of transistors of a given n or p-channel type Metal Oxide Semiconductor (MOS) transistor having a U-shaped gate electrode. The gate electrode of the transistors in each row of transistors of the sense amplifier is offset from those in a previous row by a preselected amount. The bit lines passing through the sense amplifier are straight, with no offsets to affect photolithographic performance, and no protuberances to increase the capacitance of the bit lines. Such an array of sense amplifiers has a size equivalent to the minimum size of the pairs of bit lines, and thus does not cause any increase in the width of the array of memory cells.
