DESCRIPTION

The Hynix HY57V653220B is a 67,108,864-bit CMOS Synchronous DRAM, ideally suited for the memory applications

which require wide data I/O and high bandwidth. HY57V653220B is organized as 4banks of 524,288x32.

HY57V653220B is offering fully synchronous operation referenced to a positive edge of the clock. All inputs and out-

puts are synchronized with the rising edge of the clock input. The data paths are internally pipelined to achieve very

high bandwidth. All input and output voltage levels are compatible with LVTTL.

Programmable options include the length of pipeline (Read latency of 2 or 3), the number of consecutive read or write

cycles initiated by a single control command (Burst length of 1,2,4,8 or full page), and the burst count

sequence(sequential or interleave). A burst of read or write cycles in progress can be terminated by a burst terminate

command or can be interrupted and replaced by a new burst read or write command on any cycle. (This pipelined

design is not restricted by a `2N` rule.)
