Electronic device, controller for accessing a plurality of chips via at least one bus, and method for accessing a plurality of chips via at least one bus

A controller for accessing a plurality of chips via a bus, wherein the bus comprises a plurality of data lines, the controller comprising:

• a storage unit, for storing a plurality of allocations for data transmission corresponding to the plurality of chips, respectively, where each of the allocations for data transmission is an arrangement of a plurality of bits of external data transmitted on the plurality of data lines;
• and
• a microprocessor, for accessing the plurality of chips, and selecting one of the plurality of allocations for data transmission according to information about which chip the external data will be written to, and transmitting the external data to the chip according to a selected allocation for data transmission.

A method for accessing a plurality of chips via a bus, wherein the plurality of chips comprise a first chip and a second chip, and the bus comprises a plurality of data lines, the method comprising:

• receiving external data;
• and
• determining an allocation for data transmission of external data according to information about which chip the external data will be written to, where the allocation for data transmission is an arrangement of a plurality of bits of the external data transmitted on the plurality of data lines, and a first allocation for data transmission corresponding to the first chip is different from a second allocation for data transmission corresponding to the second chip.
