Preliminary
HY5Y5A6D(L/S)F(P)-xF
4Banks x 4M x 16bits Synchronous DRAM
DESCRIPTION
The Hynix Low Power SDRAM is suited for non-PC application which use the batteries such as PDAs, 2.5G and 3G cellular
phones with internet access and multimedia capabilities, mini-notebook, handheld PCs.
The Hynix HY5Y5A6D(L/S)F(P) is a 268,435,456bit CMOS Synchronous Dynamic Random Access Memory. It is organ-
ized as 4banks of 4,194,304x16.
The Low Power SDRAM provides for programmable options including CAS latency of 1, 2, or 3, READ or WRITE burst
length of 1, 2, 4, 8, or full page, and the burst count sequence(sequential or interleave). And the Low Power SDRAM
also provides for special programmable options including Partial Array Self Refresh of a quarter bank, a half bank,
1bank, 2banks, or all banks, Temperature Compensated Self Refresh of 15, 45, 70, or 85 degrees oC. 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).
Deep Power Down Mode is a additional operating mode for Low Power SDRAM. This mode can achieve maximum power
reduction by removing power to the memory array within each SDRAM. By using this feature, the system can cut off
alomost all DRAM power without adding the cost of a power switch and giving up mother-board power-line layout
flexibility.
