Title: Refresh device for dram
Inventor: HIROYA TAKAYUKI
IPC: G06F12/00
Filed: 1997-03-12
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption further without performing a refresh operation for a memory cell region being not required to hold data in a refresh device of a DRAM having a self-refresh function. SOLUTION: The last row address 512 corresponding to a memory cell region, in which refresh of memory data is required is latched to a row address latch register 14, gates G0-G10223 are gate-controlled corresponding to this latch row address. Since a refresh signal from a refresh original signal generating circuit 22 is successively supplied for only row address lines (Row Add 0, Row Add 1,...Row Add 511) corresponding to the latch row address 512 as count operation of a 10 bits counter 21, surplus power consumption accompanied by self-refresh can be eliminated without performing refresh operation for a memory region, in which data holding is not required.
