Abstract:
1. A memory system, comprising: an array of re-programmable non-volatile memory cell charge storage elements, a plurality of control lines extending across the array, individual control lines being field coupled with both a plurality of charge storage elements thereunder and another plurality of charge storage elements under control lines adjacent thereto, a reading circuit that reads the states of the charge storage elements under an addressed control line by applying a read voltage to the addressed control line and either a second or third voltage to the control lines adjacent thereto, the second and third voltages being different from each other, and a controller operably connected with the control lines and the reading circuit to cause data to be read from the charge storage elements under the addressed control line while the second voltage is applied to the adjacent control lines and to check the read data for error, and, as a response to discovery of an error in the read data, to cause the data to then be re-read from the charge storage elements under the addressed control line with the third voltage applied to the adjacent control lines.
