2Mx16 CellularRAM

Preliminary

Functional Description

In general, CellularRAM devices are high-density alternatives to SRAM and Pseudo SRAM products, popular in low-power, portable

applications. The 32Mb device contains a 33,554,432-bit DRAM core, organized as 2,097,152 addresses by 16 bits.The device

implements the same high-speed bus interface found on burst mode Flash products. The CellularRAM bus interface supports both

asynchronous and burst mode transfers. Page mode accesses are also included as a bandwidth-enhancing extension to the

asynchronous read protocol.

Power-Up Initialization

32Mb CellularRAM products include an on-chip voltage sensor used to launch the power-up initialization process. Initialization will

configure the BCR and the RCR with their default settings. (See Figure 16 and 20) Vcc and VccQ must be applied simultaneously.

When they reach a stable level at or above 1.7V, the device will require 150

µs to complete its self-initialization process. During the

initialization period, CE# should remain HIGH. When initialization is complete, the device is ready for normal operation.
