The BSL variant offers faster 45ns speed compared to the 70ns LL variant, suitable for applications requiring both low power and fast access.","working_principle":"Fully static asynchronous SRAM. Six-transistor CMOS cells retain data without refresh. Read\/write timing follows standard async SRAM protocol.
