Re: Looking for SPI RAM (not EEProm)

Try looking at FRAM from Ramtron.  www.ramtron.com   Dallas Semiconductor (Now part of Maxim - www.maxim-ic.com ) makes a one wire ram but I'm unsure as the size   Cheers Jeremy ----- Original Message ----- From: Robert E. Griffith To: Multiple recipients of list CHIPDIR-L Sent: Monday, January 13, 2003 1:18 PM Subject: Looking for SPI RAM (not EEProm) I am looking for a serial (preferably SPI) plain RAM in an SO8 package. Preferably 8 bit wide by 16k or 32k.  Anyone know of such a chip and where I can get it?  Digi-key does not have anything like it.   I am using an SPI serial EEPROM (AT25128) attached to a 18F252 to add memory to store a large sting table.  It does not need to be persistent but I was unable to find any serial plain RAM.  Does it exist?  If not, is there a reason?  My problem is that at 100K write cycles, it will ware out too soon in my application.  The slower writes is acceptable.   I am considering switching to a parallel RAM, but I would rather not give up the board space switching an SO8 for an SO32 which would also require switching to the larger 40 pin 18F454 to get more I/O.  On the subject of parallel, does anyone make a 8 bit wide parallel RAM that multiplexes address and data on just 8 pins?   Thanks,   --BobG     -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
