Abstract: In embodiments described herein, a memory architecture has an array of non-volatile memory cells and a pair of independently controlled voltage pumps. The pair of voltage pumps is coupled for supplying both positive and negative voltage biases to the memory array during program and erase operations, such that a sum of the magnitudes of the positive and negative voltage biases is applied across a storage node of an accessed memory cell.

Abstract: Bandgap reference (BGR) circuits and methods are described herein for providing high accuracy, low power Bandgap operation when using small, low voltage devices in the analog blocks of the BGR circuit. In some cases, chopped input stabilization and dynamic current matching techniques may be combined to compensate for input voltage offsets in the operational amplifier portion and current offsets in the current mirror portion of the Bandgap circuit. When used together, the chopped stabilization and dynamic current matching techniques provide a significant increase in accuracy, especially when using small, low voltage devices in the analog blocks to reduce layout area and support low power supply operation (e.g., power supply values down to about 1.4 volts and below).

Abstract: A method for providing at least 2 Meg of SRAM cells having a maximum average operating current of approximately 9.43 mA comprising the steps of (A) providing an address path configured to consume a maximum average operating current of approximately 2.38 mA, (B) providing one or more sense amplifiers configured to consume a maximum average operating current of approximately 0.91 mA, (C) providing one or more bitlines configured to consume a maximum average operating current of approximately 0.94 mA and (D) providing a Q path configured to consume a maximum average operating current of approximately 0.61 mA.

Abstract: A circuit comprising a memory array and a logic circuit. The memory array may be configured to read or write data in response to (i) one or more enable signals and (ii) one or more control signals. The logic circuit may be configured to generate the enable signals in response to one or more address signals. De-assertion of one or more of the enable signals generally reduces current consumption in the memory array.

Abstract: A circuit comprising a memory array and a logic circuit. The memory array may be configured to read or write data in response to (i) one or more enable signals and (ii) a global signal. The logic circuit may be configured to generate the enable signals in response to one or more address signals. De-assertion of the enable signals generally reduces current consumption in the memory array.
