Title: Semiconductor device
Inventor: TAKAHASHI TAKESHI
IPC: H01L21/331
Filed: 1989-09-19
Abstract: PURPOSE:To reduce collector capacitance, and to inhibit a Kirk effect by composing a collector layer of an N-type semiconductor layer and a P-type semiconductor layer, arranging an N-type semiconductor layer having a conductivity type reverse to a base layer on the base layer side and disposing a P-type semiconductor layer having a conductivity type reverse to a sub-collector layer on the sub-collector layer side. CONSTITUTION:A sub-collector layer 14 is formed onto a semi-insulating GaAs substrate 16 through a buffer layer 18. A P-type semiconductor layer 12b and an N-type semiconductor layer 12a are shaped onto the sub-collector layer 14 respectively. When bias voltage is applied, the N-type semiconductor layer 12a and the P-type semiconductor layer 12b are reversely biassed, and a depletion layer spreads in the whole region of a collector layer 12. Consequently, collector capacitance is determined only by the thickness of the collector layer 12, and collector capacitance can be lowered in the same manner as an HBT having I-type collector structure. The N-type semiconductor layer l2a having a conductivity type reverse to a base layer 10 is shaped as the collector layer 12 on the P<+> type base layer 10 side, thus preventing the generation of a Kirk effect, then improving the high-frequency characteristics of a semiconductor device.

Abstract: PURPOSE:To realize a high-speed data cache control system by changing the data on a data cache only and inhibiting the writing action of a main memory in case the writing action of the local data received from a CPU has a hit in the data cache. CONSTITUTION:When a micro-CPU 1 writes data, the write-through processing, etc., are applied to the global data and only the data on a data field 38 is changed for the local data in case of having a hit with no writing action applied to a main memory 2. When the muCPU 1 carries out an instruction to cancel a local area against a stack, a G/L flag 35 of a data cache 3 where the present task number is coincident with a task number 36 is set at G (global). A present flag 39 of the local area of the cache 3 is set when a writing action is applied to the local area and then produces a trap to inform an abnormal access in case the CPU 1 reads the local data while no flag 39 is set. Thus the access speed is improved to the local data.
