Abstract
A memory chip, a memory controller, and an operating method of the memory chip are provided. The memory chip includes a plurality of pins; and an interface circuit configured to receive a swap command set from a memory controller through the plurality of pins, obtain a swap command and a swap address from the swap command set, generate a swap enable signal based on the swap command and the swap address, and swap and output a data signal according to the swap enable signal.
Claims21
1-26. (canceled)
A memory controller connected to a chip, wherein the memory controller is configured to:
- transmit a status check command to the chip, and receive a first value from the chip as a response to the status check command,
- when the first value is the same as a second value stored in a register of the chip, determine a swap mode of the chip as a first state, and
- when the first value is a value obtained by swapping the second value, determine the swap mode of the chip as a second state.
An operating method of memory controller connected to a chip, comprising:
- transmitting a status check command to the chip;
- receiving a first value from the chip as a response to the status check command;
- when the first value is the same as a second value stored in a register of the chip, determining a swap mode of the chip as a first state, and
- when the first value is a value obtained by swapping the second value, determining the swap mode of the chip as a second state.
A memory chip comprising:
- a plurality of pins;
- and
- an interface circuit configured to receive a swap command set from a memory controller through the plurality of pins, obtain a swap command and a swap address from the swap command set, and swap a data signal input from the plurality of pins according to the swap command and the swap address in a command-type swap mode,
- wherein at least one of the swap command set or the swap command and the swap address comprises a palindrome.
