Apparatuses and methods for storing and writing multiple parameter codes for memory operating parameters

A method, comprising:

• storing in a first register associated with a mode register a first parameter code for a first operating parameter used to set a first memory operating condition;
• storing in a second register associated with the mode register a second parameter code for the first operating parameter used to set a second memory operating condition;
• storing in a third register associated with the mode register a third parameter code for a second operating parameter used to set the first memory operating condition;
• storing in a fourth register associated with the mode register a fourth parameter code for the second operating parameter used to set the second memory operating condition;
• and
• setting a current memory operating condition based on the first and third parameter codes or the second and fourth parameter codes.

A method, comprising:

• determining a first parameter code for a first operating parameter for a first operating condition of a memory;
• writing to the memory the first parameter code to a first register for the first operating parameter;
• determining a second parameter code for the first operating parameter for a second operating condition of the memory;
• writing to the memory the second parameter code to a second register for the first operating parameter,
• determining a third parameter code for a second operating parameter for the first operating condition of a memory;
• writing to the memory the third parameter code to a third register for the second operating parameter;
• determining a fourth parameter code for the second operating parameter for the second operating condition of the memory;
• and
• writing to the memory the fourth parameter code to a fourth register for the second operating parameter.
