Filed: 1988-03-16
Granted: 1995-05-25
Abstract: For testing memory cells (SZ), all the bit lines (BL, BL) are led to a pair of error lines (FLA, FLB). This pair of lines is initially precharged with mutually complementary logic levels. All the memory cells (SZ) of one word line (WL) are always read out in parallel with one another. If "in order", the pair of error lines (FLA, FLB) retains its logic states; in the event of an error, one of the error lines (FLA; FLB) changes its logic state by means of switching transistors (ST). This is detected and evaluated by a comparator circuit (VGL), designed as an XOR or XNOR circuit. A corresponding method is likewise presented.

Abstract: The polyester resin compsn. is prepd. by adding common  glass fiber, org. fire retardant material,  fire  retadant  accelerator, antioxidant   and   impact   resitant   improving   agent   within polybutylene terephthalate; then adding  1-10  wt.%  (w.r.t  total amt.) of the heat stabilizer of formula  (I),  and  1-10  wt.%  of halogenated polyethylene  as  a  anti  dropping  agent  (pref.  of formula (II)), and 1-10 wt.% of xylene dichloride as  a  hardening agent. In formulas, M is Na, Mg, K, Fe, Cu; R is the same  or  not radical or Br, F, Cl. The obtd. resin compsn.  has  good  improved fire retardant and impact resistant properties.
