Title:
MEMORY CONTROLLER, NONVOLATILE MEMORY DEVICE, ACCESS DEVICE, AND NONVOLATILE MEMORY SYSTEM
Document Type and Number:
WIPO Patent Application WO/2008/018446
Kind Code:
A1
Abstract:
Without corresponding to different address spaces between an access device
(100) and a nonvolatile memory device (200), the access device (100) designates
a file ID to manage a data storing state only in a physical address space in the nonvolatile
memory device (200). The access device (100) sends the nonvolatile memory device
(200) a transfer rate through a transfer rate transmitting unit (121). A filling-up
rate calculating unit (251) calculates a filling-up rate of a physical block
corresponding to an assurance speed required by the access device (100). A remaining
amount corresponding to the transfer rate is sought by using the calculated filling-up
rate and is transmitted to a remaining amount receiving unit (122) of the access
device (100).
