Abstract
A storage device and memory accessing method configure two separate memory units, each with dedicated I/O channel, accessible by two controllers, each corresponding to an interface connected to a host, and allows the storage device to establish at least two connections to the different hosts. As more than one connection is established between the storage device and the hosts at the same time, a first controller has both read and write accessibility to a first memory unit and a second controller has both read and write accessibility to a second memory unit, while the first controller has read-only accessibility to the second memory unit and the second controller has read-only accessibility to the second memory unit.
