Master slave managed memory storage

A system comprising:

• memory to store data for a host device;
• a first slave port to communicate with the host device;
• a first master port to communicate with a slave storage device;
• and
• a controller configured to:
• receive, on the first slave port from the host device, a first request regarding a first storage capacity of the memory;
• in response to the first request, determine that the slave storage device is coupled to the first master port;
• in response to determining that the slave storage device is coupled to the first master port, send, to the slave storage device, a second request regarding a second storage capacity of the slave storage device, wherein the slave storage device is configured to:
• in response to receiving the second request, determine that no storage device is coupled to a second master port of the slave storage device;
• and
• in response to determining that no storage device is coupled to the second master port, send the second storage capacity to the first master port;
• receive, on the first master port, the second storage capacity;
• add the first storage capacity and the second storage capacity to provide a total storage capacity;
• and
• in response to the first request, send, on the first slave port, the total storage capacity to the host device.

A method comprising:

• receiving, from a host device by a first storage device, a command and an address associated with the command;
• determining that the address exceeds a first storage capacity of the first storage device;
• in response to determining that the address exceeds the first storage capacity, decrementing the address by the first storage capacity to provide a modified address;
• sending, to a second storage device, the command and the modified address, wherein the second storage device is configured to:
• in response to receiving the command, determine that the modified address is within a second storage capacity of the second storage device;
• in response to determining that the modified address is within the second storage capacity, execute the command;
• and
• send, to the first storage device, a result from executing the command;
• receiving, by the first storage device from the second storage device, the result;
• and
• in response to receiving the command from the host device, sending the result to the host device.
