Methods for mitigating power loss events during operation of memory devices and memory devices employing the same

A memory device, comprising:

• a non-volatile memory comprising a plurality of memory cells;
• and
• a controller configured to:
• begin a first programming operation configured to program a plurality of bits of information to a first one of the plurality of memory cells, wherein the first one of the plurality of memory cells has been previously programmed with one or more additional bits of information,
• terminate the first programming operation in response to receiving a command from a connected host device to switch from a high-density operation mode to a high speed and/or a lower power mode, and
• program, with a second programming operation, a second one of the plurality of memory cells with the plurality of bits of information.
