thanks eric for information
do u know about pspice simulation for 4 cells of 1 bit cmos sram
actually l wrote it in pspice but l have problem in bias point
(

.model lt nmos (Kp=1e-4,Vto=-2.5,lambda=1e-5,Cbd=3e-12,Cbs=3e-12,Cgso=4e-7,Cgdo=6e-9,Cgso=6e-9)
.model at pmos (Kp=1e-4,Vto=2.5,lambda=1e-5,Cbd=3e-12,Cbs=3e-12,Cgso=4e-7,Cgdo=6e-9,Cgso=6e-9)

can u help me ?
