wanted dram controller for use with mc hc for an upcoming project i want to use megs of dram configured as two meg banks of bit data i was wondering if anyone out there knows of a dram controller which will handle refreshing the data it s ok if the controller doesn t handle bank switching that part is easy the only controllers i know of are the ones out of the national semiconductor dram management handbook edition eg dp i would like to know if another manufacturer produces one which may be easier to implement in my circuit btw if anyone is wanting to hook up dram to a microcontroller dallas semiconductor makes a neat chip the ds serial dram nonvolatizer chip it uses the spi i c bus and refreshes controls up to mx of dram memory it can use an external battery to refresh the dram when the power is off price is from dallas quan i wish i could use this chip but its maximum spi clock rate is mhz too slow for me thanks in advance wayne schellekens schellew wu wl aecl ca wayne schellekens ve wts internet schellew wu wl aecl ca aecl research ax ve wts ve kv wpg mb can whiteshell laboratories twisted pair x
