Abstract
A system is capable of assisting in reset of a data storage array including data storage array including one or more data storage array nodes. The system includes a control unit coupled to the data storage array configured to produce a control signal to reset the data storage array, and a reset unit communicatively coupled to the data storage array and the control unit configured to reset the data storage array by charge injection to the one or more data storage array nodes.
Claims35
A system for resetting a data storage array comprising at least one data storage array node, the system comprising:
- a control unit coupled to the data storage array and configured to produce a control signal to reset the data storage array;
- and
- a reset unit coupled to the data storage array and said control unit and configured to reset the data storage array by charge injection to said at least one data storage array node, the charge injection including injecting positive charge into a portion and negative charge in an other portion of the data storage array.
A storage device comprising:
- a data storage array comprising at least one data storage array node and a plurality of memory cells coupled thereto;
- a control unit coupled to said data storage array and configured to produce a control signal to reset said data storage array;
- and
- a reset unit coupled to said data storage array and said control unit and configured to reset said data storage array by lowering a reference voltage of a portion of said plurality of memory cells to a negative voltage level by injecting charge to said at least one data storage array node.
A method of operating a system for resetting a data storage array comprising at least one data storage array node and a plurality of memory cells coupled thereto, the method comprising:
- producing a control signal to reset the data storage array;
- and
- using a reset unit coupled to the data storage array to reset the data storage array by charge injection to the at least one data storage array node, the charge injection including injecting positive charge into a portion and negative charge in another portion of the data storage array.
A system for resetting a data storage array comprising at least one data storage array node, the system comprising:
- a control unit coupled to the data storage array and configured to produce a control signal to reset the data storage array, the data storage array comprising a plurality of memory cells, and word lines and bit lines coupled thereto for operation;
- and
- a reset unit coupled to the data storage array and said control unit and configured to reset the data storage array by charge injection to said at least one data storage array node and by lowering a reference voltage of a portion of said plurality of memory cells to a negative voltage level by injecting negative charge.
A method of operating a system for resetting a data storage array comprising at least one data storage array node and a plurality of memory cells coupled thereto, the method comprising:
- producing a control signal to reset the data storage array;
- and
- using a reset unit coupled to the data storage array to reset the data storage array by charge injection to the at least one data storage array node, the resetting comprising lowering a reference voltage of a portion of the plurality of memory cells to a negative voltage level by injecting negative charge.
