Abstract: The disclosed technology generally relates to semiconductor devices, and more particularly to a standard cell semiconductor device comprising transistors having vertical channels and a common gate. In one aspect, a standard cell semiconductor device comprises a substrate, a unit cell having a first transistor and a second transistor, a gate layer common to the first and second transistor, and a set of routing tracks for contacting the first and second transistor. Each one of the first and second transistors is formed of a stack of layers arranged between at least some of the routing tracks and the substrate, wherein each stack comprises a bottom terminal arranged on the substrate, a channel arranged on the bottom terminal and a top terminal arranged on the channel. The channel of the first transistor is an N-type channel, and the channel of the second transistor is a P-type channel.

Abstract: A memory cell is disclosed, comprising a static random-access memory, SRAM, bit cell, a first resistive memory element and a second resistive memory element. The first resistive memory element is connected to a first storage node of the SRAM bit cell and a first intermediate node, and the second resistive memory element connected to a second storage node of the SRAM bit cell and a second intermediate node. Each one of the first intermediate node and the second intermediate node is configured to be supplied with a first supply voltage via a first transistor and a second supply voltage via a second transistor, wherein the first transistor and the second transistor are complementary transistors separately controllable by a first word line and a second word line, respectively. Methods for operating such a memory cell are also disclosed.

Abstract: The disclosed technology generally relates to semiconductor memory devices, and more particularly to a static random access memory (SRAM) device. One aspect of the disclosed technology is a bit cell for a static random access memory (SRAM) comprising: a first and a second vertical stack of transistors arranged on a substrate. Each stack includes a pull-up transistor, a pull-down transistor and a pass transistor, each transistor including a horizontally extending channel, the pull-up transistor and the pull-down transistor having a common gate electrode extending vertically between the pull-up transistor and the pull-down transistor and the pass transistor having a gate electrode being separate from the common gate electrode. A source/drain of the pull-up transistor and of the pull-down transistor of the first stack, a source/drain of the pass transistor of the first stack and the common gate electrode of the pull-up and pull-down transistors of the second stack are electrically interconnected.
