Memory controller, memory card, and nonvolatile memory system

A nonvolatile memory system comprising:

• a memory card including a nonvolatile memory and a memory controller for writing data into the nonvolatile memory, the nonvolatile memory including a plurality of physical blocks;
• and
• host equipment for providing to the memory card an access instruction that designates a logical address and a channel number,
• wherein the memory controller includes:
• an address conversion unit for converting the logical address into a physical address in the nonvolatile memory;
• and
• a write destination determination unit for obtaining a physical address in the nonvolatile memory to which the data is to be written,
• a physical block in which the physical address belongs is designated by the channel number, and
• data having a same channel number are written in a same physical block designated by the same channel number.

A memory controller which writes data into a nonvolatile memory in accordance with an externally provided access instruction that designates a logical address and a channel number, the memory controller comprising:

• a control section;
• and
• a memory interface circuit, coupled to the control section, for communicating with the nonvolatile memory, wherein:
• the control section is configured to convert the logical address into a physical address in the nonvolatile memory, and obtain a physical address in the nonvolatile memory to which the data is to be written,
• a physical block in which the physical address belongs is designated by the channel number, and
• data having a same channel number are written in a same physical block designated by the same channel number.
