AI Technical Summary
Technical Problem
When existing memory systems retrieve internal data, vendor-specific commands are not supported by general operating systems, resulting in low communication speeds and inefficient out-of-band communication, making it difficult to efficiently provide internal data.
Method used
By introducing a controller into the memory system, management data is written to a dedicated area of non-volatile memory based on write commands from the host, and a correspondence is established with user data. Internal data is provided using in-band communication, avoiding dependence on vendor-specific commands.
Benefits of technology
It enables the efficient provision of internal data without relying on the host operating system, improving the speed and efficiency of data acquisition.

Abstract
A memory system and a control method capable of efficiently providing internal data are provided. A controller is configured to write first data to a first storage area based on a first write command from a host, determine a logical address allocated to the first data written, read out internal data generated by the controller included in management data from a second storage area, write the read-out internal data to a first storage location of the first storage area, establish correspondence between the first storage location and the logical address, read out the internal data from the first storage location in response to a case where a read command specifying the logical address is received from the host, and transmit the internal data read out from the first storage location to the host.
