ABSTRACT:
A data access controller has an SRAM adapted to hold two ECC blocks so that the SRAM is used efficiently for multiple kinds of processes. At playback of data, writing of ECC block A from a demodulator and an ECC process for ECC block B begin simultaneously. When the ECC process ends, release of the ECC block B to the outside begins. When the writing of ECC block A ends, the ECC process for the ECC block A begins and, at the same time, writing of ECC block B from the demodulator begins.
