Abstract
A memory system includes a controller that recognizes, as a command, a signal received immediately after a chip select signal is received from a host device, and a memory that includes a plurality of blocks. When the command is a first command, the controller outputs to the host device, information indicating whether at least one of a write operation and an erase operation with respect to at least one particular block is prohibited.
