I was musing today about the old recirculating stores

Suppose one wanted simulate one in modern components. How would you
do it, if you had, say, a million bits to store?
CCD memory, e.g., 16 pieces of Intel 2464.
Would you use a 1x1Mb DRAM and a counter to cycle
through the
addresses? Or an 8x128Kb SRAM with an external 8 bit shift register?
Oh, *that* modern. If I was just building one, I certainly wouldn't
bother with DRAM. Is there some reason you don't want to use a 1Mx1
SRAM, e.g., Cypress CY7C1007D-10VXI?
