摘要
A priority-based flash memory control apparatus for XIP in a serial flash memory, a memory management method using the same, and a memory chip thereof. Efficient memory management is provided by assigning priorities to respective pages of a serial flash memory and storing the pages retrieved from the serial flash memory in a system memory or cache memory according to their priority. A memory management method using the flash memory control apparatus according to the present invention includes, if a request for reading data at a given logical address is received from a main control unit, searching for the data at the corresponding logical address by referring to a predetermined address translation table; and reading the data at the corresponding logical address from a system memory or a cache memory and transmitting the read data to the main control unit, depending on the results of the search.
