Rank interleaving for system meta mode operations in a dynamic random access memory (dram) memory device

A method, comprising:

• receiving, by one or more memory controllers, a first request for a memory device and a second request for the memory device;
• executing, by the one or more memory controllers, the first request in a first rank of the memory device during a first time period, wherein the first time period comprises a first data access portion and a first metadata access portion;
• and
• executing, by the one or more memory controllers, the second request in a second rank of the memory device during a second time period, wherein the second time period comprises a second data access portion and a second metadata access portion,
• wherein executing the first request in the first rank and executing the second request in the second rank comprises interleaving the first request and the second request between the first rank and the second rank.

An apparatus, comprising:

• a host device configured to communicate with a memory module through a channel,
• the host device comprising one or more memory controllers coupled to the channel, the one or more memory controllers configured perform operations including:
• receiving a first request for a memory device and a second request for the memory device;
• executing the first request in a first rank of the memory device during a first time period, wherein the first time period comprises a first data access portion and a first metadata access portion;
• and
• executing the second request in a second rank of the memory device during a second time period, wherein the second time period comprises a second data access portion and a second metadata access portion,
• wherein executing the first request in the first rank and executing the second request in the second rank comprises interleaving the first request and the second request between the first rank and the second rank.
