ABSTRACT:
A buffer circuit includes a plurality of registers, a write register selector, a read register selector, and an address proximity detector. The write register selector operates in synchronism with a write clock signal and outputs write enable signals in a predetermined sequence for write-enabling the plurality of registers, one at a time. The read register selector operates in synchronism with a read clock signal and outputs read enable signals in the predetermined sequence for read-enabling the plurality of registers to be read, one at a time. The address proximity detector detects an event in which a difference between a register write-enabled by one of the write enable signals and a different register read-enabled by one of the read enable signals at a time in the predetermined sequence is equal to a predetermined value and outputs a reset signal upon detecting such event.
