A formulation of a spray applied fire-resistive engineered cementitious composite which is made by addition of polymeric fibers, vermiculite, bonding agent and lightweight aggregates to cement and water. A receiving device, upon receipt of an electronic message, locates the incorporated key and the data from which a sending device practicing the invention would have prepared it. The security module encrypts at least one document of a user, using the security key, to generate a protected document. The left and right tubes telescope to vary the depth of the stabilizer. The delay-locked loop is configured to generate an internal clock signal in response to the standby signal and the variable bias voltage signal. Portions of data are copied and stored on other word lines.
