V53C8256H45规格书详情
Description
The V53C8256H is a high speed 262,144 x 8 bit CMOS dynamic random access memory. The V53C8256H offers a combination of features: Fast Page Mode for high data bandwidth, fast usable speed, CMOS standby current.
All inputs and outputs are TTL compatible. Input and output capacitances are significantly lowered to allow increased system performance. Fast Page Mode operation allows random access of up to 512 (x8) bits within a row with cycle times as short as 21 ns. Because of static circuitry, the CAS clock is not in the critical timing path. The flow-through column address latches allow address pipelining while relaxing many critical system timing requirements for fast usable speed. These features make the V53C8256H ideally suited for graphics, digital signal processing and high performance computing systems.
