BIT LINE SETUP AND DISCHARGE CIRCUIT FOR PROGRAMMING NON-VOLATILE MEMORY

摘要

PURPOSE: A bit line setup and discharge circuit for programming non-volatile memory is provided to decrease a noise in a power supply voltage and a ground by decreasing a peak current during a charge and discharge of bit line in a programming operation. CONSTITUTION: An array of memory cell(110) includes a plurality of bit lines and a plurality of word lines. The plurality of bit lines are connected with a column array of memory cell. The plurality of word lines are connected with a row array of memory cell. A bias circuit connected with the plurality of bit line includes a control circuit(210,220). The control circuit(210,220) controls a current flow of a switch in case a voltage of the switch and a voltage of a set of the plurality of bit line vary simultaneously.
