Abstract
A method and apparatus for accessing a non-volatile memory cell. In some embodiments, a memory block provides a plurality of memory cells arranged into rows and columns. A read circuit is configured to read a selected row of the memory block by concurrently applying a control voltage to each memory cell along the selected row and, for each column, using a respective local sense amplifier and a column sense amplifier to successively differentiate a voltage across the associated memory cell in said column to output a programmed content of the row.
