Product Summary
The LH52B256-70LL is a kind of high-density 262,144 bit static RAM organized as 32k x 8. The RAM is fully static in operation. An efficient design is obtained with a CMOS periphery and a matrix constructed with polysilicon load memory cells. High frequency design techniques should be employed to obtain the best performance from this device. Solid, low-impedance power and ground planes, with high-frequency decoupling capacitors, are recommended. Series termination of the inputs should be considered when transmission line effects occur.
