DESCRIPTION
It is organized as 4,096 words by 8 bits. The M2732A is honsed in a 24 pin Window Ceramic Frit-Seal Dual-in-Line package. The transparent lid allows the user to expose the chip to ultraviolet light to erase the bit pattern. A new pattern can be then written to the clerice by following the programming procedure.
