Abstract: A method for improving message storage efficiency of a network chip, a device, and a storage medium are provided. The method comprises: configuring a data memory, dividing the data memory into N small RAMs, and managing respective RAMs by means of a link list; in a case where a write data request is received on any input interface, parsing and acquiring a channel number corresponding to the input interface, accessing a channel write state memory according to the channel number to acquire channel write state information, in a case of determining, according to the channel write state information, that at least one RAM is null, writing data into the data memory; and in a case where a read-out scheduling request is received on any channel, recombining data according to memory information in a link list memory and reading the recombined data out.
