Question about Flash memory components: are there chips with Serial AND Parallel

[jvcastel]

Greetings to all fellows at EEVblog,

I'm interested into en EEPROM replacement, that is to take out an EEPROM and put a Flash memory instead. I saw that ther are several Flash memory devices that are pin compatible with the old 27CXXX Memory IC's and PCB designs to do this also. Now my question goes onto this: are there Flash devices than could be programmed as a serial device either via SPI or I2C and read as parallel memory by the host System? That way the host reads it as an old EEPROM but could be programmed by a Microcontroller if needed? Am I dreaming of something that doesn't exist? I appreciate your comments on this. Thanks!

Parallel FLASH with JTAG can usually be programmed over JTAG, but it's difficult and slow.
