Some of the 18F family, perhaps 18FxxJxx parts, use an emulation=20
library. But traditionally for large amounts of data an external I2C or=20
SPI part is used. At least one 18F  part is 1Mbit Flash, so 64k program=20
words. 4K program space would allow 8K bytes, though I don't know what=20
the limit on emulation library is. But you can write your own emulation=20
library for PIC18F or PIC32
