Problems solved by technology

Also, unlike optical drives, SSDs have the problem that even when data is to be stored, the data should be transferred to the host and retained therein
Therefore, the memory drive also has the problem that even when data is written to the memory drive for distribution, the data can be easily erased
[0010] Also, in the case where the memory drive includes an SSD, the memory drive also has the problem that it cannot be used in an electronic device using an optical disc drive.

Embodiment Construction

[0052] A method of writing data to and reading data from a solid state drive including a flash memory and a flash controller according to an embodiment of the present invention will be described below.

[0053] Figure 4 is a diagram showing the inside of the flash controller of the present invention. The flash controller 310 includes a host interface 311 and a flash interface 312 . Also, the flash controller 310 includes a sector manager 313 , an attribute manager 314 and a write / read controller 315 .

[0054] The sector manager 313 manages the unit of writing / reading of the flash memory 300 on a unit of writing / reading basis according to the optical disc drive standard. The write / read controller 315 writes data to or reads data from the flash memory 300 based on units of write / read managed by the sector manager 313 .

[0055] The attribute manager 314 manages attribute information assigned to the solid state drive. The attribute information may be stored in the flash mem...

Abstract

The present invention relates to a memory drive that can be virtualized as an optical disk drive and a virtualizing method thereof. One embodiment of the present invention discloses a method for virtualizing a memory drive as an optical disk drive, the memory drive comprising a storage memory and a storage memory controller, which reads or writes data from and to the storage memory. Therefore, according to one embodiment of the present invention, a solid-state drive which comprises a flash memory and a flash memory controller can be used like an optical disk.

Description

technical field [0001] The present invention relates to a memory drive capable of being virtualized as an optical disc drive and a method of virtualizing the memory drive. The present invention can control the data writability of the memory drive according to the type of the optical disc drive. Accordingly, the present invention relates to a memory drive capable of operating like an optical disc drive and a method for virtualizing the memory drive. Background technique [0002] A flash memory is a nonvolatile memory like a hard disk, has a fast access speed, and consumes less power, and thus, the flash memory is widely used in built-in systems, portable devices, and the like. [0003] In order to perform a write operation on an already written memory sector, the flash memory must perform an operation of erasing the entire block including the corresponding sector according to its hardware characteristics. Partial programming is possible in which data is written to a portion...
