ABSTRACT:
Systems and methods are described for distributed DRAM refreshing. A method of distributed DRAM refreshing includes: refreshing a first row of memory cells in a first array of DRAM memory cells with a first row of sense amplifiers; and then refreshing a second row of memory cells in a second array of DRAM memory cells with a second row of sense amplifiers. The systems and methods provide advantages in that magnitude of power transients (noise) can be reduced. In addition, the performance can be improved when the arrays are arranged in multiple sub-groups.
