ABSTRACT:
A memory device for channel selection in a television receiver comprises a nonvolatile memory for storing at least one set of channel data and channel attendant data, and a RAM having a channel data storing part which accesses and stores all channel data stored in the nonvolatile memory. When a read tuning command is given, the nonvolatile memory is accessed in order to search addresses of the channel attendant data if a specified channel exists in the RAM. When no specified channel data exists in the RAM, the nonvolatile memory is not accessed.
