hi friends

i want to save the Ram Data into pc as hex/bin file like EEPROM or EPROM files online.

i have ram rom and uprocessor in uporc. starter board and i can offline the rom, uproc. and other components except ram.
i can connect it to any eeprom/eprom programmer what will be the interfacing . suppose ram is 58256/62256/62128..... i want its bin/hex file.
i want its interface circuit at the place of 27/28 series compatible space e/eeproms.

First, You can use zero-power RAM or RAM+RTC+Battery module, they are compatible to RAM pinout.
Second, You can make, some kind of bootloader that will send ram contents thru serial port to PC. It is possible to stop uP (in reset state) change program memory by removing and puting another program memory or changing programm memory adress to ram-download-routines, and then restart uP by removing reset signal.
