Claims23
A memory cell comprising a flexible substrate layer and a layer comprising a crosslinked mixture of an acrylic polyol, an alkylene urea-glyoxal resin, and an acid catalyst, wherein said acrylic polyol possesses an OH equivalent weight of from about 300 to about 1,500, and a glass transition temperature of from about −20° C. to about 90° C.
A memory cell comprising, in sequence, a flexible substrate layer, an adhesive layer, a first electrode in contact with said adhesive layer, a ferroelectric memory layer situated between said first electrode and a second electrode in contact with said ferroelectric layer, a buffer layer in contact with said second electrode, and a protective layer in contact with said buffer layer, and wherein said adhesive layer is comprised of a crosslinked mixture of an acrylic polyol, an alkylene urea-glyoxal resin, and an acid catalyst.
A memory device comprising a plurality of memory cells wherein each memory cell comprises a flexible substrate layer, an adhesive layer, a first electrode in contact with said adhesive layer, a ferroelectric memory layer in contact with said first electrode, a second electrode in contact with said ferroelectric layer, a buffer layer in contact with said second electrode, and a protective layer in contact with said buffer layer, and wherein said adhesive layer is comprised of a crosslinked mixture of an acrylic polyol, an ethylene urea-glyoxal resin, a butylated ethylene urea-glyoxal resin, or mixtures thereof, and an acid catalyst.
