A kind of sram storage unit and memory

Abstract

The invention discloses an SRAM storage unit and a memory, relates to the technical field of circuit design, and is used for improving data security and reducing the area and power consumption of the SRAM memory. The SRAM storage unit includes: a data latch circuit, a first switch circuit, a second switch circuit, a third switch circuit and a storage circuit. The data latch circuit has a first output terminal, a second output terminal and a switching node. The first switch circuit is connected in series between the second output terminal and the conversion node. The second switch circuit is connected in series between the first output terminal and the first terminal of the storage circuit. The third switch circuit is connected in series between the conversion node and the first terminal of the storage circuit. The second end of the storage circuit is electrically connected to the ground end. The SRAM memory includes the SRAM storage unit mentioned in the above technical solution.

Description

technical field [0001] The invention relates to the technical field of circuit design, in particular to an SRAM storage unit and a memory. Background technique [0002] In order to protect data security, once the security chip detects unauthorized access, it will cut off the power of the Static Random-Access Memory (English full name: Static Random-Access Memory, English abbreviation: SRAM) to prevent attackers from stealing data. However, the SRAM has the problem of information retention, and usually part of the information stored in the SRAM before power failure can be restored by aging imprinting. [0003] Aging imprint means that when a storage unit stores fixed data for a long time, two symmetrical metal-oxide-semiconductor field-effect transistors (English full name: Metal-Oxide-Semiconductor Field-Effect Transistor, referred to as: MOS tube) will have different degrees of degradation. Bias temperature instability (full name in English: Bias Temperature Instability, E...

AI Technical Summary

Problems solved by technology

However, the structure of the master-slave SRAM storage unit is complicated, and more control signals are introduced, which increases the area and power consumption of the SRAM memory.
