Without persistent memory, programs have to be re-entered whenever power is lost, making the device cumbersome. Persistent memory can be within the calculator or as a separate device. Programmable calculators could use more than one technique.

Famous quotes containing the words persistent and/or memory:
“The country needs and, unless I mistake its temper, the country demands bold, persistent experimentation. It is common sense to take a method and try it. If it fails, admit it frankly and try another. But above all, try something. The millions who are in want will not stand idly by silently forever while the things to satisfy their needs are within easy reach.”
—Franklin D. Roosevelt (1882–1945)
“Die two months ago, and not forgotten yet? Then there’s hope
a great man’s memory may outlive his life half a year.”
—William Shakespeare (1564–1616)
