Description

The a 33,554,432 bits synchronous high data rate DRAM organized x 262,144 words by 32 bits. The device is designed to comply with JEDEC standards set for synchronous DRAM products, both electrically and mechanically. Synchronous design allows precise cycle control with the system clock. The CAS latency, burst length and burst sequence must be programmed into device prior to access operation. In addition, it features block write and masked block write functions by making a programmable mode register and special mode register, the system can select modes to maximize its performance.
