Memory system having controller connectable to network via interface and storage system having memory systems having controllers connectable to network via respective interface

A memory system comprising:

• a nonvolatile memory;
• and
• a controller connectable to a network via a first interface and configured to:
• communicate with a first memory system via the first interface through the network, the first interface conforming to a first standard, wherein
• the controller is configured to:
• manage first account information to be used for authentication of a first account;
• receive first data that includes second account information from the first memory system;
• and
• permit access to at least a partial storage area of the nonvolatile memory when the second account information included in the first data matches the first account information.

A storage system comprising a first memory system and a second memory system,

• the first memory system including:
• a first nonvolatile memory;
• and
• a first controller connectable to a network via a first interface and configured to:
• communicate with a second memory system via the first interface through the network, the first interface conforming to a first standard;
• the first controller connectable to a host device via a second interface and configured to:
• communicate with the host device via the second interface, the second interface conforming to a second standard different from the first standard,
• the second memory system including:
• a second nonvolatile memory;
• and
• a second controller connectable to the network via a third interface configured to:
• communicate with the first memory system via the third interface through the network, the third interface conforming to the first standard, wherein
• the first controller is configured to:
• manage first account information to be used for authentication of a first account and second account information to be used for authentication of a second account;
• receive third account information from the host device;
• and
• when the third account information matches the first account information, permit access to at least a partial storage area of the first nonvolatile memory based on a request from the host device and transmit first data including the second account information to the second memory system, and
• the second controller is configured to:
• manage fourth account information to be used for authentication of the second account;
• receive the first data that is transmitted from the first memory system;
• and
• when the second account information included in the first data matches the fourth account information, permit access to at least a partial storage area of the second nonvolatile memory.
