Abstract :
A 12 K-gate ECL gate array with 36 kbit of dedicated RAM has been developed. An ECL logic cell structure with an extra transistor buried under a Vcc power bus is proposed to implement both the logic function and a memory cell. The logic part has the capability of implementing configurable RAM with up to 5.8 kbit. By employing 0.6- mu m double-polysilicon self-aligned technology, the intrinsic gate delay is 110 ps at a power consumption of 1.8 mW/gate. The address access times of dedicated RAM and configurable RAM are 3.0 and 1.8 ns, respectively. The gate array is applied to 9 K-gate logic circuitry with 35-kbit table look-aside buffer (TLB) memory using dedicated RAM and a 16-word*18-bit register file using configurable RAM.
