SYSTEM PERFORMING A BITWRITE OPERATION FOR EACH MEMORY CELL OF A FIELD PROGRAMMABLE MEMORY ARRAY AND MEMORY SYSTEM

PURPOSE: A system is provided to improve a scalability and a bit write flexibility together with minimizing an external wire necessity. CONSTITUTION: In a system for performing a bit write operation for each memory cell of afield programmable memory array, a bit write line part provides a write access for each memory cell(115). A bit write control sub array(350) has a plurality of control memory cells, each of which provides a write access for one of the memory cells in connection with the bit write line part. A data bus forms an input for the bit write control sub array for programming the bit write control sub array.
