Abstract: A nano-magnetic element array having a conductive line adjacent to a group of nano-magnetic elements and a multi-level current driver connected to an input node on the conductive line. The current driver is controlled by a pair of voltage clock signals and a voltage reference so as to selectively change the current amount at the input node between a first level that erases the state of the elements, a second level that switches the state of the elements and a third level that maintains the state of the elements. The current driver is further configured so that the transition from the second to the third level is gradual. Optionally, a bias generator can selectively adjust the voltage reference and thereby, the current amount at the input node. Also, optionally, the same voltage clock signal and voltage reference lines can be used to control multiple multi-level current drivers within the array.

Abstract: Disclosed is a memory array structure, where a wordline driver selectively applies a high on-state voltage (VWLH) or a low off-state voltage (VWLL) to a wordline. VWLH has a slightly negative temperature coefficient so that it is regulated as high as the gate dielectric reliability limits allow, whereas VWLL has a substantially neutral temperature coefficient. To accomplish this, the wordline driver is coupled to one or more voltage regulation circuits. In one embodiment, the wordline driver is coupled to a single voltage regulation circuit, which incorporates a single voltage reference circuit having a single output stage that outputs multiple reference voltages. Also disclosed is a voltage reference circuit, which can be incorporated into the voltage regulation circuit of a memory array structure, as described, or, alternatively, into any other integrated circuit structure requiring voltages with different temperature coefficients. Also disclosed is a method of operating a memory array structure.

Abstract: Apparatus and methods for signal margin centering for single-ended eDRAM sense amplifier. A plurality of DRAM cells is connected to an input side of a multiplexer by a first bitline. A single-ended sense amplifier is connected to an output side of the multiplexer by a second bitline. The single-ended sense amplifier has a switch voltage. The second bitline is precharged to a selected voltage level. The multiplexer passes a signal voltage from a selected one of the plurality of DRAM cells to the second bitline. The selected voltage level is selected such that reception of the signal voltage of a first type adjusts a voltage of the second bitline in a first direction and reception of the signal voltage of a second type adjusts the voltage of the second bitline in a second direction opposite from the first direction, centering the signal voltage around the switch voltage.

Abstract: Disclosed are embodiments of a multi-bank random access memory (RAM) structure that provides signal buffering at both the global and local connector level for improved performance. Specifically, inverters are incorporated into the global connector(s), which traverse groups of memory banks and which transmit signals (e.g., address signals, control signals, and/or data signals) from a memory controller, and also into alternating groups of local connectors, which connect nodes on the global connector(s) to corresponding groups of memory banks, such that any of the signals that are received by the memory banks from the memory controller via the global and local connectors are buffered by an even number of inverters and are thereby true signals. Signal buffering at both the global and local connector level results in relatively fast slews, short propagation delays, and low peak power consumption with minimal, if any, increase in area consumption.
