Abstract
A non-volatile memory device is disclosed, which performs a sensing operation using a current. The non-volatile memory device includes a cell array including one or more unit cells, configured to read or write data, a current-voltage converter configured to convert a sensing current corresponding to data stored in the unit cell into a sensing voltage, and perform a precharge operation of the sensing voltage upon receiving the sensing current in response to a current driving signal at an activation time point of a word line of the cell array, and a sense-amp configured to compare the sensing voltage with a predetermined reference voltage, and amplify the compared result.
