A semiconductor memory storage apparatus includes a packetization unit receiving content data includes a plurality of variable-length frames, and adding management data showing frame data inherent information to frame data of each variable-length frame, and further, packetizing the content data storing the frame data and the management data in each fixed-length packet for every variable-length frame, a buffer temporarily storing the content data at a fixed-length packet unit in write/read operation of the content data packetized at the fixed-length packet unit, a storage unit using a non-volatile memory as an information storage medium, and storing the content data supplied from the buffer, and a controller writing/reading content data packetized at the fixed-length packet unit with respect to the storage unit at a fixed-length packet unit.
