ABSTRACT:
A circuit measures current passing through a memory cell in a NAND flash memory. The circuit includes a decoder and an analog mixer. The decoder is configured to select at least one data line coupled to page buffers and column decoders in accordance with a controlling signal. The analog mixer is configured to output current passing through the selected data line, or to couple all of the data lines to a means for measuring current in accordance with a total current measurement controlling signal.
