Memory array with distributed clear transistors and variable memory element power supply

A memory element circuit, comprising:

• a bi-stable data storage element having a data storage node operable to store data;
• an address transistor operable to address the bi-stable data storage element and being coupled between a data line and the data storage node;
• and
• a clear transistor operable to clear the data storage node and being coupled between the data line and an adjustable power supply voltage.

Memory element circuitry, comprising:

• read-write circuitry operable to load data;
• a plurality of memory elements that are operable to be cleared by the read-write circuitry using clear control lines and data lines;
• and
• at least one clear transistor that is coupled to the plurality of memory elements through one of the data lines that is operable to clear the plurality of memory elements in response to control signals from the read-write circuitry, and that is supplied with an adjustable power supply voltage.

A memory element array, comprising:

• a plurality of memory elements arranged in rows and columns, each memory element having a first inverter having an input coupled to a first data storage node and an output coupled to a second data storage node, a second inverter having an input coupled to the second data storage node and an output coupled to the first data storage node, a first address transistor coupled between a first data line and the first data storage node, a second address transistor coupled between a second data line and the second data storage node;
• a first clear circuit that is only coupled between the first data line and a terminal at a first power supply voltage;
• and
• a second clear circuit that is only coupled between the second data line and a terminal at a second power supply voltage that is different than the first power supply voltage, wherein the first and second inverters are each coupled between a terminal at the first power supply voltage and a terminal at the second power supply voltage.
