摘要: This paper reports on comprehensive analytical and numerical circuit analyses on the read margin of the one selector-one resistor (1S1R) resistive-switching crossbar array. These analyses are based on the experimental characteristics of the 1S1R cells and provide a valuable insight into their potential for ultrahigh-density data storage. Three read schemes, namely, one bit-line pull-up (One-BLPU), all bit-line pull-up (All-BLPU), and partial bit-line pull-up (Partial-BLPU), are investigated. In contrast to the One-BLPU scheme, the All-BLPU scheme can realize a large crossbar array of 16 Mb, even when the line resistance is nonneg-ligible because the effective resistance at the sneak current path is substantially less sensitive to the array size. Additionally, the Partial-BLPU scheme can be used to reduce power consumption if random read access is desirable. Finally, the effects of line resistance on the read and write margins are discussed.
