ABSTRACT:
A semiconductor memory with hierarchical bit lines has a plurality of local bit lines, a plurality of global bit lines, a plurality of word lines, a plurality of memory cells each arranged at a connection portion between each local bit line and each word line, and a plurality of transfer gates. The local bit lines are connected to the global bit line through the transfer gates, which are arranged near the centers of the local bit lines. This arrangement realizes a high-speed operation and a low power consumption without increasing the number of local, bit lines.
