I am making a excercise treadmill. I am using 8051 microcontroller. I need a way to make my 8051 remember the last speed selected. Try to give a simple solution!! . No rocket science Its just a treadmill so dont take it serious.

You should consider working in a magazine writing article titles. :shock:
Your title was so dramatic that I was curious to see what was this about and then the content of the post was quite normal... I was disappointed :roll:

lol. This is called marketing . So what do you suggest?
 

Battery backup and low power mode is the easiest and viable solution as I understand.
 

A serial eeprom is smaller and more durable than a battery. You'll need to spend some lines of code for an I2C or SPI/microwire interface however.
