S29WS064R
64 Megabit (4M x 16-bit), CMOS 1.8 Volt-only
Simultaneous Read/Write, Burst-mode MirrorBit® Flash Memory
Data Sheet (Advance Information)
Distinctive Characteristics
Single 1.8-Volt read, program and erase (1.70V - 1.95V)
65 nm MirrorBit process technology
Command set compatible with JEDEC (42.4) standard
Dynamic Protection Bit (DYB)
– A command sector protection method to lock combinations of
individual sectors to prevent program or erase operations within that
sector
VersatileIO™ Feature
– Device generates data output voltages and tolerates data input
voltages as determined by the voltage on the V pin
– 1.8 V compatible I/O signals
IO
– Sectors can be locked and unlocked in-system at V level
CC
Hardware Sector Protection
Simultaneous Read/Write operation
– All sectors locked when ACC input is V
IL
– Data can be continuously read from one bank while executing
erase/program functions in other bank
– Low V write inhibit
CC
Handshaking feature
– Zero latency between read and write operations
– Provides host system with minimum possible latency by monitoring
RDY
Burst length
– Continuous linear burst
Supports Common Flash Memory Interface (CFI)
Cycling Endurance: 100,000 cycles per sector (typical)
Data retention: 10 years (typical)
– 8-word/16-word linear burst with wrap around
Asynchronous Page Mode
– 8-word page
– Page access time of 20 ns
Data# Polling and toggle bits
– Provides a software method of detecting program and erase
operation completion
32-word write buffer reduces overall programming time for
multiple-word updates
Sector Architecture
Suspend and Resume commands for Program and Erase
operations

– One hundred twenty seven 32-Kwords sectors
– Four banks
Synchronous or Asynchronous program operation,
independent of burst control register settings
– Top or Bottom boot sector configuration
ACC input pin to reduce factory programming time
Secured Silicon Sector region
Offered Packages
– 256 words accessible through a command sequence, 128 words for
the Factory Secured Silicon Sector and 128 words for the Customer
Secured Silicon Sector
– 84-ball FBGA (8 mm x 11.6 mm)
