Preliminary Data
Features
■
Supply voltage – VDD = 1.7 V to 2.0 V for program, erase and read – VDDQ = 1.7 V to 2.0 V for I/O buffers – VPP = 9 V for fast program Synchronous/asynchronous read – Synchronous burst read mode: 54 MHz, 66 MHz – Asynchronous page read mode – Random access: 70 ns, 85 ns Synchronous burst read suspend Programming time – 2.5 µs typical word program time using Buffer Enhanced Factory Program command Memory organization – Multiple bank memory array: 8 Mbit banks for the M58LR128KT/B 16 Mbit banks for the M58LR256KT/B – Parameter blocks (top or bottom location) Dual operations – Program/erase in one bank while read in others – No delay between read and write operations Block locking – All blocks locked at power-up – Any combination of blocks can be locked with zero latency – WP for block lock-down – Absolute write protection with VPP = VSS
