ABSTRACT:
The present invention proposes a non-volatile semiconductor storage, comprising a plurality of main bit lines, a plurality of sub bit lines connected to the main bit lines, and a plurality of memory cell arrays, each including a plurality of non-volatile semiconductor memory cells disposed like an array. Each of those memory cells has a source terminal, a drain terminal, and a control gate, and each source-drain path is connected to a sub bit line. Between a main bit line and a sub bit line connected to the main bit line is disposed the source-drain path of a first transistor, and the source-drain path of a second transistor is connected to the sub bit line.
