SRAM4

The alliedsignal SRAM4 is a radiation hardened industry standard 4096 x 1 bit static random access memory. SRAM4 is fabricated using AlliedSignal's proprietary 1.2um CMOS/SOI process which exhibits a high tolerance to radiation and temperature.The RAM operates as specified over full military temperature and requires a single 5 V(+/- 10%) supply and retains data down to 2.0 volts.

The SRAM4 has the following features including:(1)latch-up free; (2)low voltage backup mode; (3)low standby current; (4)fully static design; (5)six transistor bit cell; (6)ttl on all inputs, cmos outputs; (7)5 volt supply; (8)standard jedec d1p pfnout; (9)full mil temp (-55 to 125).Toshiba is continually working to improve the quality and the reliability of their products.Nevertheless, semiconductor devices in general can malfunction or fail due to their inherent electrical sensitivity and their vulnerability to physical stress. It is the responsibility of the buyer, when utilizing Toshiba products, to observe standards of safety, and to avoid situations in which the malfunction or failure of a Toshiba product could cause loss of human life, bodily injury or damage to property.

The absolute maximum ratings of the SRAM4 are:(1)operating current:5.0mA; (2)input capacitance:5pf; (3)input voltage low:Vss-0.7 to 0.8V; (4)input voltage high:Vdd/2 to Vdd+0.7V.The products described in this document are designed, developed and manufactured as contemplated for general use, including without limitation, ordinary industrial use, general office use, personal use, and household use, but are not designed, developed and manufactured as contemplated (1) for any use that includes fatal risks or dangers that, unless extremely high safety is secured, could have a serious effect to the public, and could lead directly to death, personal injury, severe physical damage or other loss (i.e., nuclear reaction control in nuclear facility, aircraft flight control, air traffic control, mass transport control, medical life support system, missile launch control in weapon system), or (2) for any use where chance of failure is intolerable (i.e., submersible repeater and artificial satellite).
