i did some reading.. they offer a 256Kb ( 32 kilobytes) unlimited read/write

"The 256Kb 2.7-3.6 volt FM18L08 offers virtually unlimited read/write
cycles. You can now access each address a million times per second for
hundreds of years with no wear out. "

Ramtrom rates most of their serial parts at 10^10 (10 billion)
read/writes. (I would presume that their byte-wide memories have the
same limitation but I don't have a datasheet handy to confirm this.)

They claim "unlimited read/writes" for their FM24CL16, a 2 Kbyte
serial device that runs on 2.7 to 3.6 volts Vdd.
