HY57V658020B
4 Banks x 2M x 8Bit Synchronous DRAM
DESCRIPTION
The Hynix HY57V658020B is a 67,108,864-bit CMOS Synchronous DRAM, ideally suited for the main memory applications which
require large memory density and high bandwidth. HY57V658020B is organized as 4banks of 2,097,152x8.
HY57V658020B 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 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.)
FEATURES
• Single 3.3±0.3V power supply
• All device pins are compatible with LVTTL interface
• JEDEC standard 400mil 54pin TSOP-II with 0.8mm of pin
pitch
• All inputs and outputs referenced to positive edge of system clock
• Data mask function by DQM
• Internal four banks operation
