Title:
SEMICONDUCTOR STORAGE DEVICE
Document Type and Number:
Japanese Patent JP3389124
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a semiconductor storage device capable of improving characteristics without increasing a chip size.
SOLUTION: This semiconductor storage device has a writing operation auxiliary circuit 2 which is arranged between a memory cell region 50 and a peripheral circuit region and has a cell shape. The circuit 2 has a first circuit 4, which conducts a discharge operation of digit lines during the start of a writing and a precharge operation of the digit lines during the completion of a writing, and a second circuit 5 which conducts a discharge operation of digit lines and conducts the switching of discharging operation of the digit lines.
