Programmable non-volatile semiconductor memory device

摘要

The present invention relates to a programmable non-volatile semiconductor memory device comprising a matrix of rows and columns of memory cells ( 1 ). To reduce the required memory area a 3T memory cell is proposed comprising a bridge of two bridge transistors (MN 0, MN 1 ), preferably NMOS transistors, a read transistor, preferably an PMOS transistor, and a silicided polysilicium fuse resistor (R). The read transistors enable the use of a single sense line (SL) for all memory cells ( 1 ) of the same row or column in the matrix thus enabling the use of a common sense amplifier for sensing memory cells ( 1 ).
