Computing system with communication mechanism and method of operation thereof

1. A computing system comprising:

a host memory including a driver and an address map;

a host central processing unit, coupled to the host memory, configured to:

divide a command to a command packet with the driver,

map the command packet to the address map,

deliver the command packet based on the address map over a command address medium separate from a data medium to request a status information from the host memory; and

deliver the command packet over a volatile memory interface for a non-volatile device.

2. The system as claimed in claim 1 wherein the host central processing unit is further configured to:

deliver the command for a write based on the address map to request the status information; and

issue a further command for a read of the status information.

3. The system as claimed in claim 1 wherein the host central processing unit is further configured to access a bank of the address map.

4. A method of operation of a computing system comprising:

dividing a command to a command packet with a driver;

mapping the command packet to an address map;

delivering the command packet based on the address map over a command address medium separate from a data medium to request a status information from the host memory; and

delivering the command packet over a volatile memory interface for a non-volatile device.

5. The method as claimed in claim 4 further comprising parsing the command packet from the command address medium.

6. The method as claimed in claim 4 further comprising assembling the command from the command packet from the command address medium.

7. The method as claimed in claim 4 further comprising training to calculate a protection information.

8. The method as claimed in claim 4 further comprising receiving a protection information over a data medium.

9. The method as claimed in claim 4 wherein:

delivering the command packet includes delivering the command for a write based on the address map to request the status information; and

further comprising:

issuing a further command for a read of the status information.

10. The method as claimed in claim 4 wherein delivering the command packet includes accessing a bank of the address map.

11. The method as claimed in claim 4 further comprising ordering the command packet to assemble the command.

12. The method as claimed in claim 4 further comprising not receiving the command packet over a data medium.

13. The method as claimed in claim 4 further comprising providing a non-volatile storage.
