Read latency control circuit
摘要:
The invention provides a method for setting and controlling a read latency (L) by means of a FIFO-based read latency control circuit for a read access to a semiconductor memory, having the method steps of providing a common internal clock signal; generating an internal first clock signal and an internal second clock signal, which is different from the first clock signal, from the common clock signal; generating an output pointer for reading out the read data from the first clock signal; generating an input pointer for reading in the read data from the second clock signal; initializing the input and output pointers by allocating a defined, fixedly predetermined time offset between output pointer and input pointer. The invention furthermore provides a corresponding circuit arrangement for carrying out the method.
