You could, but it's far easier to do it via just one pin and use a serial transfer method, if you have PIC's with hardware USART's it's even easier. But even with a software UART it's still plenty fast enough for most purposes.
wich memory is generally used instead of a i2c eeprom and is faster???
i need to write and read very fast..(faster as 1ms)
It depends on what you are trying to do?, you can always simply connect a static RAM to a PIC, using the PIC pins to provide the address and data lines.
Go to digikey.com and do a search on SRAM. You can use their great search utility to find the right ram chip. Parrallel ram is the fatest but SPI(or 3 wire) ram should be fast enough for a 1ms read and write even i2c ram should be fast enough.
which issue was it. of all the issues i have i could only find one oscilloscope project which came in the October 2000 issue. it also used the 16F877 but it used the TC55257DPL-85L 32K Byte SRAM.

I'd have to look back for the magazine, I read the chip number off the actual chip - I didn't use the same chip as the original design, it had been discontinued. I confirmed the one I did use was a suitable repalcement via email.
