Final answer:
PROM is the type of memory chip that allows the end user to write information to the memory only one time and then preserves that information indefinitely without the possibility of erasure.
Step-by-step explanation:
The type of memory chip that allows the end user to write information to the memory only one time and then preserves that information indefinitely without the possibility of erasure is PROM (Programmable Read-Only Memory).
PROM is a non-volatile memory chip that can be programmed by the end user once with specific information or data. Once programmed, the information on PROM cannot be erased or modified.
An example of PROM is a BIOS chip in a computer, which contains the firmware instructions required for the computer to boot up.
