Filed: 1989-08-25
Abstract: PURPOSE:To reduce the power consumption of dynamic RAM by subdividing a word line in a memory array, selecting one of the subdivided word lines at the time of reading and writing and operating a belonging sense amplifier. CONSTITUTION:The word line W in the memory array M-ARY is subdivided and the number of memories MC connected to one word line is reduced. One of the subdivided word lines is selected at the time of reading and writing, and only the sense amplifier MC on the belonging data line is operated. At the time of refreshing, plural word lines are simultaneously selected. Thus, the number of the sense amplifiers MC which are driven at the time of refresh ing does not change as conventionally, but the number of the sense amplifiers becomes small in inversely proportional to the division number of the word lines. Consequently, the number of the bits lines which are charged and dis charged by the sense amplifiers at the time of reading and writing is consider ably reduced and therefore the power consumption of dynamic RAM can be reduced.
