That shows just how much you know about calculator technology.

As any old-time HP owner will tell you, in order to make something
uneraseable, you need to snip its corner off.  If you were to crack open
your Equation Library card and examine the actual memory chips, you'd
see that the top-left corners are missing.  In the old days, this was an
unavailable part of the storage area, but technology improves, and so
today one has the choice of 100% usage, or write-protection and 98%
usage (+/-1%, dependent on the width of one's scissors).

[Note: snipping the corners off memory chips may void your warranty and,
 if performed in the presence of highly-skilled engineers, may cause them to
 laugh and poke fun at you.  That will show you just how much they know.]
