Dram controller with adaptive precharge policy

A method for controlling a Dynamic Random Access Memory (DRAM) comprising one or more memory banks, the method comprising:

• receiving 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;
• receiving 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;
• adaptively setting, based on the indications, a policy of deactivating rows of the DRAM;
• and
• executing the I/O commands in the DRAM in accordance with the policy.

A system, comprising:

• a Dynamic Random Access Memory (DRAM) comprising one or more memory banks;
• one or more clients, which are configured to issue 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, and to provide 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;
• and
• a DRAM controller, configured to receive the I/O commands and the indications from the one or more clients, 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.
