REWRITING DEVICE FOR ERASABLE PROGRAMMABLE READ ONLY MEMORY

摘要

PURPOSE:To rewrite stored contents with an erasable programmable read only memory EPROM set by directly setting a rewrite adapter, which is connected to an EPROM rewriting device main body by a cable, to the EPROM set to a package. CONSTITUTION:An adapter 2 for EPROM rewrite is attached to an EPROM 3 set to a package 6. The adapter 2 is connected to an EPROM rewriting device main body 1 by a cable 5, and stored contents of the EPROM 3 are irradiated with ultraviolet rays from a lamp incorporated in the adapter and are erased in accordance with the instruction from the device main body 1. Information which is read from a master ROM and is stored in a memory provided in the EPROM rewriting device main body 1 is sent to the adapter 2 from an incorporated ROM writer and is written in the EPROM 3. Thus, stored contents are updated with the EPROM 3 set to the package 6.
