The invention provides a semiconductor apparatus and a continuous readout method capable of achieving high speed continuous readout. The continuous readout method for NAND type flash memory of the invention includes: a detecting step of detecting a frequency of an external clock signal; a readout step of reading data from the memory cell array based on a readout timing corresponding to the frequency of the detected external clock signal; a holding step of holding the read data in a latch (L1) and a latch (L2), and an output step of outputting the held data in synchronization with the external clock signal.
