Abstract

A coding method for self-aligned mask read only memory, which is applicable to code the memory cell of mask read only memory into the first state and the second state, in which the mask read only memory includes one substrate, bit line formed on the substrate and word line insulatedly formed on the substrate and bit line, features: 1. forming shielding material on the substrate between bit lines before forming bit lines; 2. implanting dopant with the shielding material as mask to make the memory cell which is determined to form the first state form the first state, and other memory cells forming the second state.
