HY5V62CF
4 Banks x 512K x 32Bit Synchronous DRAM
DESCRIPTION
The Hynix HY5V62C is a 67,108,864-bit CMOS Synchronous DRAM, ideally suited for the memory applications which
require wide data I/O and high bandwidth. HY5V62C is organized as 4banks of 524,288x32.
HY5V62C is offering fully synchronous operation referenced to a positive edge of the clock. All inputs and outputs are
synchronized with the rising edge of the clock input. The data paths are internally pipelined to achieve very high band-
width. 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.)
