The memory dump format is a headered [[Formats#ROM_dump_formats|ROM dump format]] from the memory chips from the CPU address space, used for loading program files using Easybug, Texas Instruments

The contents of these files are taken from the CPU address space, so there must be meta-data about the origin of the data. In fact, these files are commonly 8196 bytes long, that is, 4 bytes for header information plus the common size of a ROM (8K).

'''Address'''

Memory address in the CPU address space.

'''Length'''

This word specifies the length of data. File size should be the sum of the header size (4 bytes) plus the length of data. If the file is larger, only the given length of data is used.
