CE-212M 8K
Half-size card
Sharp RAM Memory cards fit a number of their calculators. The initial series were
full-size (CE-201M, CE-202M, CE-203M). Sharp then came out with the half-size series (CE-210, CE-211, ...) which were
electrically equivalent but half the width. They also added some smaller and larger memory sizes in this second
series of cards.
While installed in a calculator, the card uses the calculator's power supply and the backup battery is not
used. The life of the backup battery is 5 years or more if the card remains in a calculator with useable
batteries.
If the card is stored removed from the calculator, the life of the backup battery is about 12 months (depending upon
the size card and the ambient temperature). Any program and data are lost when the backup battery is changed.
Pressing the ALL RESET button on a calculator with a RAM card will also erase the card. (NOTE: This is NOT true of
the more recent series of PROM CF Flash Memory cards.)
