Title: Semiconductor memory
Inventor: KIRIHATA TOSHIAKI
IPC: H01L21/8242
Filed: 1998-12-18
Abstract: PROBLEM TO BE SOLVED: To enable master bit lines to be enhanced in pitch and lessened in line capacitance, by a method wherein the master bit lines are set shorter than a row length, and some of the master bit lines covering memory cells are set larger than local bit lines in pitch. SOLUTION: Master bit lines MBL are interleaved, and the master bit lines MBL are shortened to be half or below as long as a row, whereby the master bit lines MBL can be set wider in pitch than those of conventional technique architecture. All the capacitance of the master bit lines MBL gets smaller with a reduction in the length of the master bit line and with an increase in a space between the adjacent master bit lines. As a space is increased, inter-bit line capacitance between the adjacent master bit lines MBL is decreased, so that all the capacitance of the master bit lines MBL becomes small. When the master bit lines MBL are widened in pitch, DRAMs are improved in yield.
