ON-BOARD PROGRAMMING OF OTP EPROM
by Franco MORANDI
In recent years interest has been growing in On-Board Programming of OTP EPROM memories. There are two main factors which have stimulated this interest: the growth of the FLASH Memory market and the increased use of surface mount packages. THE GROWTH OF THE FLASH MEMORY MARKET UV EPROMs and OTP EPROMs offer a higher degree of flexibility compared to Mask ROMs. This is due to their ability to be electrically programed and, in the case of the UV EPROM, erased by exposure to UV light, then re-programed.
