APPARATUSES AND METHODS FOR STORING AND WRITING MULTIPLE PARAMETER CODES FOR MEMORY OPERATING PARAMETERS

摘要

Apparatuses and methods for writing and storing parameter codes for operating parameters, and selecting between the parameter codes to set an operating condition for a memory are disclosed. An example apparatus includes a first mode register and a second mode register. The first mode register is configured to store first and second parameter codes for a same operating parameter. The second mode register is configured to store a parameter code for a control parameter to select between the first and second parameter codes to set a current operating condition for the operating parameter. An example method includes storing in a first register a first parameter code for an operating parameter used to set a first memory operating condition, and further includes storing in a second register a second parameter code for the operating parameter used to set a second memory operating condition.
