Abstract: A static random access memory SRAM unit and a related apparatus are provided, to reduce power consumption of an SRAM when the SRAM memory is accessed. The SRAM unit is located in an SRAM memory, and the SRAM memory includes an SRAM storage array including a plurality of SRAM units. The SRAM unit includes: a storage circuit, connected to each of a write circuit and a read circuit, and configured to store data; the write circuit, configured to write data into the storage circuit; and the read circuit, configured to: after a read enabling signal is valid, enable data on a read bit line connected to the SRAM unit to be the data stored in the storage circuit.

Abstract: This application provides a flexible screen cover. The flexible screen cover includes a protective layer, a main layer, and a buffer layer. A modulus ratio of the main layer to the buffer layer is 8 to 180000. The buffer layer can be disposed at any proper position in the flexible screen. A modulus ratio of an adjacent layer to a buffer layer is 2 to 500000. The collapsible electronic device includes a housing and a flexible screen, and the flexible screen is installed in the housing. This application can improve impact resistance performance of the flexible screen.
