Abstract:
A refresh address generator may include a lookup table including a first portion storing a first group of addresses associated with a first data retention time, and a second portion storing a second group of addresses associated with a second data retention time different from the first data retention time, wherein the addresses of the first portion are more frequently accessed than the addresses of the second portion to refresh the memory cells corresponding to the addresses. Systems and methods may also implement such refresh address generation.
