How to realize storing Data 10k-20kb

[Robson]

Thanks for fast reply,
but how´s about the timing speed with serial eeprom´s? After a byte is written i need to include a waitstate of 10ms or not?
If i´m using a 4 MHz osc and a baudrate of 9600 up to 19200 is it possible to realize that or is the waitstate after each write not necessary?
Which kind of i2c eeproms are available > 32kbytes, and speed?
Note : The reading data should be stored on the fly !
