Introducción del producto:MT48LC4M16A2P-6A:J Presentación del producto

The MT48LC4M16A2P-6A:J is a 64-megabit synchronous DRAM from Micron Technology organized as 4,194,304 words by 16 bits. It operates at clock frequencies up to 166MHz with a -6 speed grade, providing high-bandwidth data throughput for memory-intensive applications. The device features four internal banks that can operate concurrently, programmable CAS latency of 2 or 3, and programmable burst lengths of 1, 2, 4, 8, or full page. Auto-refresh and self-refresh modes ensure data integrity, while DQM pins provide byte-level masking for read and write operations. The 3.3V LVCMOS-compatible interface and 54-pin TSOP-II package make it suitable for a wide range of networking, computing, and consumer electronic applications.

Principio de funcionamiento:MT48LC4M16A2P-6A:J Principio de funcionamiento

The MT48LC4M16A2P-6A:J operates using a synchronous DRAM architecture with three key subsystems. (1) The command decode and control logic processes inputs from CS, RAS, CAS, WE, and address lines on the rising clock edge to determine the operation mode (activate, read, write, precharge, refresh, mode register set). The mode register stores configuration settings including CAS latency, burst length, and burst type. (2) The memory array consists of four independent banks, each containing a 1Mx16 DRAM cell array with row and column decoders. The activate command opens a row in a selected bank, and subsequent read/write commands access columns within that row. (3) The data path includes a 16-bit bidirectional data bus with DQM masking, and the I/O buffers support burst-mode data transfer at the full clock rate, achieving peak bandwidth of 332MB/s at 166MHz.
