Abstract
A NOR-type read only memory with improved read-out performance includes a memory cell array having a plurality of memory cell blocks, each memory block including a plurality of bit lines, a column decoder for generating a plurality of decoding signals in response to a plurality of address signals, a first bias/ground selection control circuit for generating a plurality of first bias/ground selection signals determining bias conditions for a first group of the plurality of bit lines, a first bias/ground selection circuit for establishing bias conditions of the first group of the plurality of bit lines in response to the first bias/ground selection signals generated from the first bias/ground selection control circuit, a second bias/ground selection control circuit for generating a plurality of second bias/ground selection signals determining bias conditions of a second group of the plurality of bit lines, and a second bias/ground selection circuit for establishing bias conditions of the second group of the plurality of bit lines in response to the second bias/ground selection signals generated from the second bias/ground selection control circuit.
