MEMORY DEVICE FOR APPLICATION IN HIGH-SPEED PIPELINE REED-SOLOMON DECODER, MEMORY ACCESS METHOD AND REED-SOLOMON DECODER COMPRISING THE MEMORY DEVICE

摘要

PURPOSE: A memory device for application in a high-speed pipeline Reed-Solomon decoder, a memory access method and a Reed-Solomon decoder comprising the memory device are provided to increase the memory access speed in a high-speed block pipeline Reed-Solomon decoder to operate a memory device at a high speed. CONSTITUTION: A RAM(180) having six banks comprises a cyclic buffer controller(300) and a bank block(301). The bank block(301) comprises first to six banks (310-360). The cyclic buffer controller(301) outputs a read/write command(RD/WR) and a bank selection signal(BS) to the first to six banks(310-360). The bank signal(BS) for selecting one of the six banks(310-360) is composed of three bits. The bank selection signal(BS) is termed address. The read command(RD) is a signal commanding the reading of data stored in a selected bank, while the write command(WR) is a signal commanding the writing of data into the bank selected by the bank selection signal(BS).
