Abstract

A circuit includes a Vdd node, and a two-port Static Random-Access Memory (SRAM) cell pair having a first SRAM cell and a second SRAM cell having a same structure. The first SRAM cell is a ten-transistor SRAM cell that comprises a first pull-up transistor and a second pull-up transistor, a first pull-down transistor and a second pull-down transistor forming a latch with the first pull-up transistor and the second pull-up transistor, a first pass-gate transistor and a second pass-gate transistor connecting to the latch, a p-type isolation transistor including a first source/drain region connecting to a drain region of the first pull-up transistor, and a gate connecting to the Vdd node. The circuit further includes a read bit-line shared with the second SRAM cell. and a write bit-line pair connecting to gates of the first pass-gate transistor and the second pass-gate transistor.
