| 20100135085 | MULTI-LEVEL MEMORY CELL UTILIZING MEASUREMENT TIME DELAY AS THE CHARACTERISTIC PARAMETER FOR LEVEL DEFINITION - A computer program product for operating a memory cell and memory array. The computer program product of memory cell operation entails receiving a request to read a binary value stored in the memory cell. A pre-charging operation pre-charges a bit-line capacitor in an electronic circuit formed by the memory cell to a pre-charge voltage. A word-line in the electronic circuit is then activated. A discharging operation discharges the bit-line capacitor through the said memory cell in the electronic circuit to the word-line. Additionally, an electron discharge time measurement is started when the word-line is activated. The electron discharge time measurement is stopped when the voltage level in the bit-line falls below a pre-defined reference voltage. A determining operation determines the binary value from the measured electron discharge time. | 2010-06-03 |
