SEMICONDUCTOR DEVICE
Document Type and Number:
Japanese Patent JP2014139995
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce an occupied area of a bit line equalization circuit while maintaining precharge characteristics.SOLUTION: A semiconductor device comprises equalization circuits EQ which include: diffusion layer regions SDT1, SDB1 in which contact conductors CE1, CE2 for connection with bit lines BLT1, BLB1, respectively are installed; a diffusion layer region SDEQ which extends in an X direction and to which precharge potential is supplied; and linear gate electrodes G for connecting the diffusion regions each provided at a boundary between every diffusion region. The diffusion layer regions SDT1, SDB1 are isolated from each other.
