On a 1993 subaru impreza ecu board where is the eprom located and what does it look like?

mine is a 93 impreza, it is underneath the passenger's footwell under the carpet. Think I heard for newer models it is in the dash area on the driver's side.

Why eeprom is better than eprom?
The advantages were "accumulative", so a history of the development of ROM is best to explain them: First came ROM - Read-Only Memory. Unlike RAM, ROM could not be written to but had the advantage that it was non-volatile which means its contents are permanently there, they do not disappear when power is removed. But the contents were put there in the factory, you could not "program" the contents yourself. Then came PROM - Programmable ROM. With PROM you could, if you owned a programming machine or "programmer", set the contents of the PROM yourself, one time, before your put it in the electronic circuit board. Next came EPROM - Eraseable PROM - with EPROM if you needed too you could take the EPROM out of the circuit board, put it in an EPROM eraser to reset the contents, and then program it again in the programmer. The EPROM eraser was a small box that the EPROM was placed inside. When the box was turned on ultra-violet light shined into the EPROM thorough a small "window" on the top of each EPROM, erasing the contents. Finally came EEPROM or E2PROM - Electronically Erasable PROM. With EEPROM you didn't need the eraser or the programmer! The EEPROM can be programmed, again and again while it is on the circuit board, by sending a sequence of signals to certain pins on the device.
What is the meaningful of eprom?
EPROM stands for Erasable Programmable Read Only Memory.
Which type of data is present in EPROM?
Cannot be universally answered, it depends on the current EPROM. It might be empty as well.
Is eprom permanent memory?
Permanent
What are the examples of NOR flash Memory?
EPROM
When there is a calibration update available for an obd-ii vehicle the old Eprom is removed from its socket in the pcm and a new Eprom with the update software is installed in its place?

What are the 2 main types of ROM called?
PROM (programable read only memory) EPROM (eraseable programable read only memory) PROM (programable read only memory) EPROM (eraseable programable read only memory) PROM (programable read only memory) EPROM (eraseable programable read only memory) PROM (programable read only memory) EPROM (eraseable programable read only memory) PROM (programable read only memory) EPROM (eraseable programable read only memory) PROM (programable read only memory) EPROM (eraseable programable read only memory)
What type of memory that can be reprogrammed?
CMOS, EEPROM and EPROM
Where are post instructions stored?
Power On Self Test instructions are part of the BIOS that is stored in EPROM. Some of the parameters used by the EPROM are stored in the BIOS CMOS chip.
A ROM chip that can be programmed over and over using ultraviolet is known as what?
EPROM or Erasable Programmable Read Only Memory was invented by Engr. Dov Frohman. It is a ROM-type chip that can hold data from 10-20 years. It is different from PROM because it can be programmed more than once. An EPROM programming is erased only through exposure to ultra violet light. The EPROM is configured or reconfigured using an EPROM programmer.
What are the similarities between ROM and EPROM?

What are the kind of ROM?
ROM can be broadly of three types, namely PROM (programmable read only memory), EPROM (erasable PROM), and EEPROM (electrically EPROM). Many versions of EEPROMs are available.
