Abstract
A buffer controller includes a pointer generator, a code converter, a synchronizer, a code restorer, and a comparator. The pointer generator operates according to a first clock signal, and generates a first pointer by encoding a first address of a buffer with a first code. The code converter generates a first transmission pointer by converting the first pointer with a second code or a third code according to an amount of data stored in or read from the first address. The synchronizer synchronizes the first transmission pointer with a second clock signal. The code restorer generates a first comparison pointer by restoring the first transmission pointer, synchronized with the second clock signal, with the first code. The comparator compares the first comparison pointer with a second pointer. The second pointer defines a second address of the buffer with the first code.
