Ferroelectric random access memory (FeRAM) plays a vital role in information storage due to its unique advantages, driving the demand for high-capacity and high-density solutions. In this paper, a series of PbZr1-xTixO3 (x = 6 %, 8 %, 10 %, 12 %, 14 %) films were prepared using sol-gel and spin-coating methods. As the Ti content increases, the enhancement effect of the ferroelectric order is reflected structurally in XRD and Raman spectra, and electrically in the dielectric and ferroelectric properties. Notably, for x = 12 %, the P-E hysteresis loop exhibits slightly pinched and double-like, and the peaks of the I-V curve are split on both the positive and negative field sides. This ferroelectric behavior is caused by an underlying triple-well free-energy landscape, which is the basis of tristate ferroelectric memory. The measurement results show that the "±1" and "0" states of PbZr0.88Ti0.12O3 film under electric field cycling exhibit excellent programmability. It also achieves promising data retention up to 1000s and endurance up to 107 cycles. This investigation not only verifies the feasibility of applying tristate ferroelectric memory to PZT-based films but also provides a facile method for fabricating tristate ferroelectric memory devices. © 2025 Elsevier Ltd and Techna Group S.r.l.
