Bloch line memory might have eventually developed to the capacity of
modern flash memories, and probably not had the wear-out problem.
They never would have reached the read performance of flash, but might
have kept up with the write performance.
Bulky, power-hungry and expensive, mostly--and slow random-access, as it
was recirculating.
On the other hand, the only thing that seems to be holding MRAM and FRAM
back is density. TI is aggressively marketing MSP430 MCUs with embedded
FRAM.
