A Dynamic Random Access Memory (DRAM) controller includes a memory interface and a processor. The memory interface is configured to communicate with a DRAM including one or more memory banks. The processor is configured to receive Input/Output (I/O) commands, each I/O command addressing a respective memory bank and a respective row within the memory bank to be accessed in the DRAM, to further receive one or more indications, indicative of likelihoods that a subsequent I/O command will address a same row in a same memory bank as a previous I/O command, to adaptively set, based on the indications, a policy of deactivating rows of the DRAM, and to execute the I/O commands in the DRAM in accordance with the policy.
