S27KL0641, S27KS0641
HyperRAM^™ Self-Refresh DRAM
3.0V/1.8V 64 Mb (8 MB)
Distinctive Characteristics
HyperBus™ Low Signal Count Interface
 3.0V I/O, 11 bus signals
– Single ended clock (CK)
 1.8V I/O, 12 bus signals
– Differential clock (CK, CK#)
 Chip Select (CS#)
 8-bit data bus (DQ[7:0])
 Read-Write Data Strobe (RWDS)
– Bidirectional Data Strobe / Mask
– Output at the start of all transactions to indicate refresh
latency
– Output during read transactions as Read Data Strobe
– Input during write transactions as Write Data Mask
