... A power failure during a WRITE cycle may corrupt data at the currently addressed location, but does not jeopardize the rest of the RAM's content. At voltages below V user can be assured the memory will write protected state, provided the V is not less than t . The M48Z35/Y may respond to transient noise spikes on V ...
