    Abstract: Disclosed are a method and apparatus for controlling a cache memory in an electronic device. The apparatus includes a cache memory having cache lines, each of which includes tag information and at least two sub-lines. Each of the at least two sub-lines including a valid bit and a dirty bit. A control unit may analyze a valid bit of a sub-line corresponding to an address tag of data when a request for writing the data is sensed, determine based on activation or deactivation of the valid bit whether a cache hit or a cache miss occurs, and perform a control operation for allocating a sub-line according to a size of the requested data and write the data when the cache hit occurs.
