Such cells do not always need to be fully refreshed; a low-latency partial refresh is sufficient for them. We propose Variable Refresh Latency DRAM (VRL-DRAM), a mechanism that fully refreshes a DRAM cell only when necessary, and otherwise ensures data integrity by issuing low-latency partial refresh operations.
This paper proposes a new memory architecture to reduce the power consumption by refresh operations by slowing down the refresh rate.
We propose AVATAR, a VRT-aware multirate refresh scheme that adaptively changes the refresh rate for different rows at runtime based on current VRT failures.
Based on comparing the existed refresh strategies:the uniform refresh strategy,the personal refresh strategy and classified refresh strategy,we propose a new classified refresh strategy which uses both the popularity and the freshness of web pages. Moreover,we demonstrate its optimization and efficiency in theory.

However, simply doing intelligent scheduling of refresh operations is ineffective at obtaining significant performance improvement.

To reduce refresh penalty we propose techniques referred collectively as “Coordinated Refresh”, in which scheduling of low power modes and refresh commands are coordinated so that most of the required refreshes are issued when the DRAM device is in the deepest low power Self Refresh (SR) mode.

Completely tracking multiple types of refresh information (e. g., row retention time and data validity) maximizes refresh reduction and lets us choose the most effective refresh schemes.
In this paper, we propose Refresh-Oriented Prefetching (ROP) to alleviate memory refresh overheads.
However, at higher traffic rates, a proactive routing protocol can perform better with an appropriate refresh parameter.
In this work, we propose a simple, practical, and effective refresh approach called CAR (Compression-Aware Refresh) to efficiently mitigate refresh overheads.
