Byte Magazine described an "erase-only memory" circuit in it's "What's New" section:
The Stanislowski Electronics 3131.3 is a 4 Kbyte, vigorous, random-access erase-only memory (RAEOM) Imaginary Metal Oxide Semiconductor (IMOS) integrated circuit (IC)... Possible applications include disposing of obsolete data and programs, destroying incriminating evidence, and amusing computer hobbyists. Due to the patented IMOS process, the 3131.3 remains fully functional even when power is removed, making it ideal for use during power blackouts.
