ZBT architecture eliminates the dead bus cycle between read and write transitions. ## Commercial temperature grade: 0°C to 70°C The operating temperature range of 0°C to 70°C places this SRAM in the commercial grade. It is not rated for industrial enclosures or outdoor cabinets.","metaTitle":"Micron MT55L256L18F1T-12TR 4Mbit ZBT SRAM, 9 ns Access Time","metaDescription":"MT55L256L18F1T-12TR is a 4Mbit ZBT SRAM from Micron with 9 ns access time, 83 MHz operation, parallel interface, 100 TQFP.
