Filed:

May 2, 2003

Appl. No.:

10/428742

Inventors:

Hung Nguyen - Fremont CA, US
Sang Nguyen - Union City CA, US
Elbert Lin - Fremont CA, US
Anh Ly - San Jose CA, US

International Classification:

G11C011/34

US Classification:

365/185210

Abstract:

A non-volatile memory semiconductor device has a circuit to compensate for the variation in the data pattern to be programmed. The variation in the data patter creates a variation in the current requirement. The array receives a plurality of data pattern signals which affect the total amount of current flowing into a plurality of columns and into the memory array. A high voltage source generates an output which is supplied along a conducting path connected to the group of columns. A pass transistor is in the conducting path controlling the current flow in the conducting path. A current source has a first terminal and a second terminal with the first terminal connected to the output of the high voltage generator and the second terminal connected to the gate of the pass transistor. A plurality of current sources are collectively connected to a node. Each of the plurality of current sources receives a plurality of second signals with each second signal being an inverse of the first signal, and controlling the total amount of current flowing through the node. A current mirror circuit is connected to the node and to the gate of the pass transistor and controls the pass transistor in response to the amount of current flowing through the node.

Abstract:

A non-volatile memory device has a charge pump for providing a programming current and an array of non-volatile memory cells. Each memory cell of the array is programmed by the programming current from the charge pump. The array of non-volatile memory cells is partitioned into a plurality of units, with each unit comprising a plurality of memory cells. An indicator memory cell is associated with each unit of non-volatile memory cells. A programming circuit programs the memory cells of each unit using the programming current, when fifty percent or less of the memory cells of each unit is to be programmed, and programs the inverse of the memory cells of each unit and the indicator memory cell associated with each unit, using the programming current, when more than fifty percent of the memory cells of each unit is to be programmed.
